Title: speedmaster aluminum heads and roller rockers
Post by: mygasser on April 14, 2026, 10:13:45 AM
before i start please don't let this dissolve into another china bashing thread. i'm in the uk so any heads i buy will be 'overseas' so....
 has anyone used speedmaster aluminum heads and/or their aluminum roller rockers? i've got my roller cam and lifters now so i'm thinking why not get better heads and rockers now. it'll mean the 'to order' pushrods won't have to reordered if i do the change later so..... makes sense to me anyway. the plan has always been to fit aluminum heads later so why not do it once.
neil.

I'll be straight with you, dude.

The SpeedMaster/ProComp/et al is junk.  And yes, it's cheap Chinese junk, just like the lifters you bought. 

I don't use their stuff, but have seen plenty of it fail:  heads can't pass a pressure test, seats need valve job, guides fall out, roller rocker arms spit out needle bearings, distributors fail.

It's cheap for a reason.  You play the game, roll the dice, and see if it works for you.

They literally copied/stole ideas/designs from hard-working companies, such as Edelbrock, MSD, CHI, Parker, etc., then produced them very poorly.

That is their MO.  They can go play in traffic.

and another "I agree"

Had a set of their SBF heads come through here last week, sent them on their way.  Absolute crap

Their rockers are known to have body and adjuster failures, also crap

Of note, the guys who are all responding build LOTS of engines.  Take free advice for what you paid for it, but we know junk and avoid it.

If you're trying to be frugal, find someone with a set of Edelbrocks that they're selling to upgrade to something else.   

You don't need roller rockers.  I've got engines out there with hundreds of passes on them running factory non-adjustable and factory adjustable rockers, with end stands added.

Speedmaster is terrible both from a quality standpoint and also from their business practices.

Cheap is rarely good.

The parts are really core to the maintenance of the FE in the sport.  I wouldn't rule out farming out the casting to an overseas enterprise and doing the machine work in your shop.
Title: Re: speedmaster aluminum heads and roller rockers
Post by: RustyCrankshaft on April 20, 2026, 08:37:43 PM
True you are in the UK and any head will be "overseas". I guess the real question is do you want to spend money on a gamble you'll get a useable part from Speedmaster (my personal experience is that's a poor bet), and even though everything for you is overseas would you prefer to spend your money with a country that hates you, or one that is friendly?

There are better options available. Since everything will have to be freighted to you, there are lots of good used Edelbrocks or similar if you aren't in a hurry.

Although I try to avoid chinese stuff when possible, it isn't always. At least outfits like Scat are ding their own quality control and machining. Speedmaster is just terrible in every respect.

I do have to give credit to Summit for fixing the issue. Not that they aren't without flaws, but Summit is at least still a privately held company that does a pretty good job in the modern world of keeping their business here compared to selling to some investment company.

Promaxx heads are pretty decent, they put quality valves in them and the machine work is nice or it least a set of SBC that we installed for a customer were,, our local machine shop was impressed with the off shore pieces and said everything checked out good (BTW they hate Speedmaster).

The Chinese can produce good stuff- if you pay them to. They build stuff to the price point they are paid for- which is usually "cheap". South Korea produces some VERY nice stuff if you pay them to- I have a Korean 6-speed transmission in my Indian, the castings are very nice, very quiet, absolutely no leaks, shifts excellent- just a nice piece

i never knew promaxx did fe heads. i just had a look on their website and the maxx 170 head set up for hyd' roller cam would be most suited for my 390 build. cheaper than edelbrock rpm heads and with bigger valves and smaller chambers. thanks for the tip.
so has anyone got any experience with the promaxx fe heads?

Be sure they clear your bore and valve reliefs.  Especially the exhaust side for the valves, not much room on a 390 bore, or even a 428

Sorry for being parochial, but I still can't support a Chinese casting regardless of it being finished at home just to save a buck.  I know it's a sign of the times, but 25.5 years in the military and seeing that emboldened theft in so many ways, they won't come through my shop, even if I lost a sale (or multiple).

   I have a set of PROMAXX heads on my street 427 Starliner. I've had zero problems with them. Valve train geometry came in with minimal shimming. 72cc chamber with the smaller of their valve size options. Compared to the big "H" low riser heads with larger valves I would say I now have an extra 1,000 very strong RPM.

agreed, but they seem to be approx' $1000 more (50%) than the promaxx heads. i'm not building a track car, it's just a fun driver so although the best would be great if i can't afford the best..... i often say to people it doesn't matter how much of a bargain something is, if you don't have the money it's still unfortunately too expensive.

For the base model ProMaxx head, you get not much more than Edelbrock performance.  You pay a lot to not get much.

Sorry Frank, I floated right by your post. It's a solid poke.

It is extremely unfortunate, and yes, looks to be speaking out of both sides of my mouth.  Add SCAT, Eagle and K1 to that mix too, and there are many more.  I hate it, I do try to avoid it when there is a US-made substitute as in this case. Not to mention, using Molnar stuff it isn't to save money either, so yet again another difference, if we had a US made alternative, I'd jump. In fact, my most recent build for myself (452 in the Cobra) runs Crower rods.

We are all forced to use some things with manufacturing in China.  My only counter is that I draw the line at known stolen designs.  That is the absolute main reason that I would kick those heads out of the shop, same with the intakes.  It doesn't make it much better, but at least the R&D costs are paid for by the manufacturer who then profits here.  The Stevens heads and whoever is making the intakes, as well as all the  Speedmaster stuff, and all the names it changed from, stole all kinds of stuff from MSD, from Parker, from Edelbrock, you name it without legal right to it.  It'd be criminal if done in the US between two US companies. 

Keep in mind the manufacturer sent a set to me and I think to Brent too, I had my chance for input.  Not interested then and not now.  Just think if Jay's intake adapter shows up for 150 bucks?  Should we buy them? Certainly not an unlikely scenario, easy when it's a company, how about if it's a friend like Jay?.

BTW I wouldn't be mean to anyone about choices they make to pay their bills, I just wouldn't do an engine if someone asked to do that top end, and man I hope some of my best customers don't ever ask :)

However, eventually it will fix itself, cost to entry will be too high in the US due to lower volume and nobody will do the R&D on anything that isn't high volume production, cool US made parts will stop and China won't create them on their own.

I'll throw my couple of pennies in here....

Molnar is a step *up* in price and quality, not like buying a SpeedMaster product.  Molnar is superior to Scat, Eagle, etc., and you pay for it.  You're not setting out to buy it because it's half the price of others, like SpeedMaster.

In addition, in reference to speaking out of both sides of one's mouth, I'll note that Frank likes to poke engine builders about using Molnar rods under the guise of being foreign-country-conscious, but on other forums will be quick to talk about how great certain South Korean products are.

BTW, besides Crower still making rods, Carillo and Oliver still make rods. What company hasn't copied the H beam Carrilo rods?

If you want to keep American rod manufactures in business , those are the rods that should be in quality builds.

So Brent, Before you speak for me, I would suggest that you reference the actual the thread you speak of or, give a direct quote from it! That is NOT what I said, at all. As a matter of FACT, I did not say anything about how great ANYTHING was!

Prove me wrong or apologize.

https://www.speed-talk.com/forum/viewtopic.php?t=68807

"BBM or Bear Block Motors is the best source for CI FE blocks.

You can call for availability at 818 349 0999

The FE is basically limited to 4.38 x 4.38 or 528 ci but, they are lighter and more compact.

Heads can run up to ~400 cfm and there is a new aluminum Tunnel Port head available at this time, un-ported they flow 354 cfm @ .700" "



There ya go, Frank.  Where I'm from, calling a company the best source for something is giving your stamp of approval on it.  Great....best....pretty much synonyms if I read my thesaurus correctly. 

We can go further:  the definition of "best" is:  the superlative of good or well, defining something as superior in quality, highest in performance, or most desirable and appropriate. It means surpassing all others, offering the maximum advantage, or representing the highest effort. Common synonyms include optimal, top-tier, finest, premier, and superior.

You completely skipped by Robert Pond Motorsports, who also makes cast iron blocks, and casts them in the US.    Again, you are very critical when someone mentions Molnar rods, but are very quick to recommend a supplier based out of South Korea, while glancing over obvious choices in the United States.  The clincher is that you don't have experience with any of them.  You are giving blind recommendations just based off of stuff you have read on the internet, which adds a little more fuel to the fire.

Just let me know which side of your mouth you'll be retorting with. 

Have a good one.

If you want to keep American rod manufactures in business, those are the rods that should be in quality builds.   

I think you are crossing streams. 

1 - No two rods I have seen are alike, other than close similarity to K1 and Molnar, who were business associates.  Even then, the bolt design is a bit different.  I am not buying into your claim of everyone copying.  If we want to speculate I bet we could find some old Duesenberg or some other 30's car that had an H-beam capscrew long ago.  That being said, yes, I sure would like to use all-American stuff, but we have to be realistic in what we stand for and against.

2 - As an engine builder, I cannot justify spending more than what the engine needs, I give them the option and explain off shore sourcing, but to add 400+ for rods above a Molnar (or more than that as an upgrade from SCAT I-beams) is usually a show stopper.  I would prefer to use a fully USA-made rod, but I have to accept an engine is an expense, not an investment, in fact, I have to often remind customers that, so in turn they trust and expect us to tell them when something is sub-par or overkill.  In this case, the middle is Molnar, K1, and Callies offshore (although I shy away from Callies because they are heavy).  Lesser like SCAT H-beam is very capable but heavy, I try to avoid those unless the customer has them.  Eagle....well, when you have a set machined right, they are OK but heavy too, but when you have to resize a few you get turned off quickly and cost goes up. 

3 - However, despite that, I can refuse to use parts.  Don't bring a Procomp or Speedmaster part in.  That decision can cost me if the customer leaves, and that's OK, I will be respectful and understand the position but I won't use Speedmaster stuff, both based on business practices and failures.  I also won't use highjacked stuff.  If it seems like I pick and choose, I do.  American company tasks Chinese company to build something because it's cheaper...I don't like it, but I get it.  Chinese company copies something and keeps trying until an Amercian company accepts it and badges it...different.

My opinion is this.  If you want to sit and snipe at my comments, continue, I'll keep playing

However, if you want to do a Speedmaster build and go all the way up to the Promaxx heads, 200 dollar and Speedmaster rockers, go for it.  Let us know how it runs and lasts and how much labor you had to add to the build

Additionally, you could build an all American engine with no offshore sourcing.  I'll applaud you, but it'll be a lot of money and that's a very hard decision to make on an average Joe's budget.

I never said anything about how "great" they were, just that, at the time, they were the best source available! PLUS, they are not made in China!!! Like the products that you and Ross put in engines.

I have never promoted anything made in China!

Ross, you will tell people to hit the road because they want to use the Pro Maxx head that cost $1000 less than the TFS and say you "have" to use the Molnar rod because it cost $400 more than a American one?

I don't think many people realize the Molnar rod is made in China, in part, at least, because both of you use them and promote them but, say you won't use Chinese stuff.

Hey everybody, I use Molnar rods.  They are forgings from China, machined in the US.  They're a better quality than most other rods out there and you pay extra for the quality.  I also use Scat cranks, because I don't believe in asking someone to pay $5000 for a custom billet crankshaft from Bryant/Winberg to build a 445/482 or spending thousands to have a factory crank customized and end up with a re-machined 60 year-old crankshaft.

In addition to all of that, yes, I realize they're made in China, but there are quality products coming from China and non-quality products coming from China. 

The quality parts coming from China include AFR cylinder heads, Molnar rods, Scat cranks, Callies Compstar rods, etc., etc. 

The non-quality parts coming from China include SpeedMaster/Procomp, etc., etc. 

As Frank brow-beats everyone from his computer/phone that was made in China about using Chinese products, I'll just skirt around all of that and tell you all that I can set you up with a full rotating assembly using Scat cranks, Scat rods, Molnar rods, etc., and it will be pretty affordable for someone who wants to build a new 445/482/496/510, etc. 

Have a good day!

China or Taiwan?  There used to be a difference between the two.  I spent time on Taiwan helping the Taiwanese people refurbish the F4-C/D/E aircraft with battle damage.  Good people to work with and good work ethics.  You could leave your tool bag on an aircraft wing at end of shift and everything would be there the next day exactly as you left it.  No where else in the world is that possible.  JMO, but to me there is a great difference when you say Chinese made and made in Taiwan.  Joe-JDC

I don't think many people realize the Molnar rod is made in China, in part, at least, because both of you use them and promote them but, say you won't use Chinese stuff.

First, I don't tell anyone to hit the road, I discuss options and if we are not on the same page, we both agree.  It's NEVER angry as you would like to make it sound.  I have seen guys come in with boxes of old pistons, heads that have been butchered, all you can do is advise, then we decide who is willing to carry the risk.  If I won't put my name on it, I don't do it.

If someone came in and wanted to use Promaxx, I would explain why I do not use any of the Stevens castings. TFS isn't the only game in town. If they insisted, I would offer Edelbrocks, repair/improvement of stock, or recommend some other guys who may be willing.  Very regularly, and similar, people come in excited about Speedmaster rockers, I won't use them either, but all I have to do is push them to Google.

As far as the Molnar rods, the range of rods, using a 6.70 BBC journal.   In order for a street stroker, I like SCAT I-beam, Molnar/K1, then expensive, for lack of a better term.  Most of the time you can get away with a SCAT I-beam for the builds I usually do.  However, if I am doing a steel crank, big dollar build, the strength and weight of the Molnar is an advantage over the I-beam, so we discuss.  The 400-dollar number is if we considered wanted to go a step higher than Molnar for US made, not the other way around.  Unfortunately, that next step is significantly more money than Molnar and then it goes back to the US-made vs US-machined discussion.

You don't live in this world, I am sure it's similar in tool making, but we aren't ladies of the evening that get paid for whatever pleasure someone asks for.  There are times a dingle ball hone and re-ring may be the right answer for the customer's budget, but I'm not doing it, just advising the risk and if needed, send them to someone who will.

Let me put one more thing out there, especially regarding rods:

If you don't buy the American product, there is no incentive for American company's to make make one and if you don't request additional products, there will never be any options made, to any base product that might still be made in the good old USA.

Think about it.

Frank, no doubt.  Are you going to run only USA made and sourced parts for the ones you are working on?  A lot of aluminum from the middle east, TRW stuff in India and South America, bearings from all over the place. 

In theory, I agree, but I (and sounds like Brent too) draw the line at hijacked patents because it's nearly impossible to avoid China completely.  I don't like that part either, but there is a breaking point, and that's mine

I don't know why these conversations usually only pertain to engine parts.  Well, I kinda know, given the instigator in this thread.

Guys will throw ten shades of gray at an engine builder for using a rod that was forged offshore, but don't take the time to research if there are 100% USA made smart phones, PC's, etc.  Even current vehicles being made by Ford, Chevrolet, Dodge/Chrysler/RAM, etc., are not 100% USA stuff. 

BTW Frank, I think you're overplaying this a little too much, just to take a dig at me or Ross.  On that Speedtalk thread, you could have easily mentioned Robert Pond Motorsports.  And it may have very well been that they were out of stock on cast iron blocks at the time, but did you even take a second to list their name or mention them?  Nope.  It must not be that important to you.

What brand of cell phone do you use?  There's a cell phone, called the Liberty phone, with 100% US made components and assembly.  It's $1999.  I assume you'll be running out and buying one after you know about this now?

Agree with Ross, unfortunately nearly impossible to avoid China altogether but i defiantly wont knowingly purchase something they ripped off from someone else.

I'll add something to this. I just received a Starrett 98-6 machinist level, and they are not cheap at $182. Made in China now.

I'm not advocating China parts, but you have to be pragmatic about it.  If we closed off all Chinese production, there would be no Walmart and no Amazon.  A manufacturer who steals designs should not be rewarded just because they can undercut the original R&D manufacturer's price.

A quick little note regarding the discussion of aftermarket heads and who’s are better etc.  I bet not to many know the current B/S record holder is a ‘70 Ford Mustang 428 equipped with factory iron cobra jet heads. Stock does not allow porting of the heads and in B/S his car weighs 3290lb. Car ran a 10.08 @ 131.

US goods produced in China is a complex situation.  A while back I worked with someone who was forced out of his job in car parts sales.  Chinese companies could produce and deliver quality parts here at a price lower than his US company could buy the raw steel to make the parts.  I believe their lack of safety and environmental regulations along with cheaper labor had a lot to do with that.  Kind of ironic given how we are so concerned with global warming.  We highly regulate ourselves and end up sending manufacturing to where there's much less regulation... not sure how that reduces global warming. 

Many US design companies have employees overseas to coordinate manufacture of US designed goods because there is no (or very little) ability in many categories in the US anymore.  And that includes way more than auto parts...fabric, chemicals, pharmaceuticals, etc.

Not to mention, the Chinese government supports and sponsors corporate espionage...says our own FBI.  And there's very little US manufacturers can do about that.   

I'm sure many of you know all of this.  And it's not a rant or a political statement.  That's just the way it is and I don't see that changing without a LOT of tough choices being made by everyone.

This thread is interesting and is reoccurring fairly regularly.
It does put me into a quandary.
I did buy a China RPM for the 360 in my pickup. It fit well and works good. Got it on Ebay for $200 bucks.

My point of quandaryment is, who is my bigger enemy?
Is it the Chinaman who supposedly wants to kill me and send the American economy into a downward spiral?
Or is it the Investment Firm that bought a family owned business (Edelbrock) that's selling an intake manifold that the R&D and foundry tooling was done 30+ years ago and has decided that gouging the consumer to the tune of $700+ is the way to go?
I can't decide.
Flame away.

It's not quite as simple as you make it out. Edelbrock is located in California, so add what % just based on that? Regulations, cost of raw materials, environmental fees for U.S. based foundries, living wages for an American foundry worker (especially living in your state of Cali)....the list goes on, and on, and they all contribute to that price. Then China comes along, steals the design, pays their worker a couple bucks a day, with no environmental costs, and dumps it on the consumer....and you supported that. Seems you made your decision.

Let's face it, the US is not very competitive on many things for many reasons.
When you guys need that pacemaker or other medical device good luck finding a 100% US made unit and I bet your perspective will shift a bit on the matter.
Don't get me wrong, out right stealing an idea where the original designers name is still on the product, that is of course total BS but every company out there and every human has lived off of and advanced off of the backs of those before, inside and outside our country.  Global commerce is a good thing overall, competition is good, if it's not patent protected then what are we saying?  Hey, don't make that because I do?

Doug has a very good prospective, the added cost pays Americans for their jobs and family's.  As for the pace maker or what ever you want to say to square ones idea. No one is saying not to buy this or that . One is simply suggesting that when one can , buy American. Back 30 years ago when all the quality parts went to Mexico because every one that had a choice of a $7 dollar part,, or a $20 dollar part choice the $7 dollar one and the quality part went the way of the doh doh bird. Now you have to buy three of said part to get one the works.

I'm with Tommy on this. With the $500 that I save, I can go to my local pub and have a burger & a beer (& a lot of them). Pub owner makes out, waitress makes out. Put a few bucks more in the collection plate on Sunday. Buy a few extra boxes of Girlscout cookies and on and on. I'd rather give my local economy a boost than piss it away to make a feel good point. Edelbrock has to adapt like everyone else. Of coarse being an OG has much to do with my attitude which is generally no shi*s given.

Seems funny that for years you couldn't even buy a new product for the FE, and then Edelbrock entered the market with heads and intakes that were fairly reasonably priced.  Many folks jumped on the new parts and not long after that there was an aluminum shortage causing prices to jump on everything from pistons to intake manifolds.  However, Ford could build trucks using aluminum body panels, and many car companies had aluminum hoods, trunks and some even made of fiberglass.  So where was the shortage?  When I worked a part time job while stationed in Utah back in 1971-1975 the oil wells were shut down all over the mid-west by the government.  The wells owned by Shell oil company and others were mandated to only pump 10% or less to keep the equipment active and functioning.  Said we had enough reserves for the next 500 years and we were going to use up the World's supply and then sell ours to them.  Shortages real, or manufactured?  Prices real or inflated for quick profits?  Sometimes you buy what is available out of necessity, not what you would prefer and not quibble about where it was manufactured.  Joe-JDC

Ive seen this in my home town first hand. When company's no longer can compete they either move or close . The service industry pays almost nothing besides tips. Sure the owner makes out but pay out to its work force isn't great. The town i live in had probably 30 factory's in it up till the 90s. NAFTA killed that , now none of them are open any more. Yes there plenty of restaurants, but how many familys of 4 does that raise? I remember when those factory jobs had free or close health care, matched 401k , stock incentives etc , where are those things now days?

When folks talk about buying domestic vs overseas, thoughts understandably turn to jobs, supporting the family, etc.

We're in a position where much of the equipment and knowledge for important industries no longer exist in the US or are in the process of leaving....gone to a country that doesn't like us.

Let me point something out that many that don't remember world history, may not understand.

Do any of you remember the "Opium Wars" of the 1800's? Basically, the British tried to addict the Chinese, using Opium, from India, to control their trade with them and that is what the Chinese are doing to us today. Not only with drugs, like fentanyl, that destroy people and family's but, with cheap goods, that destroy our work force and our ability to make anything here.

Our big corporations and many small businesses, are just like those Opium addicted Chinese workers and businessmen but, their (our) Opium is profits. Kinda like the old saying "What comes around, goes around". We need to get out heads out of our a$$ and anyone that can buy American should and must, do so.

And how does a U.S. based company "adapt" to cheap slave labor with no regulations? They simply go out of business, and then people like you blame others. Your last sentence says it all.
