Best FE Heads And Why ?

[427HISS]

What manufacturer do you like the best, and why ?

Which are ready out of the box ?
Are $3,000 heads worth it ?
Is max flow the only factor that matters ?
What makes one manufacturer better than the rest ?.
Can highly polished ports make a big difference in flow ?
How much does port matching matter ?

How do you like the new AFR heads and why ?

AFR doesn’t make FE heads

[Rory428]

Pretty broad question, what is the intended application supposed to do? A mild cruiser and a 8 second drag car have vastly different head requirements, as does a .030" over 352, compared to a 520 cube engine. Kinda like asking how high is up.

Following this to see where it goes... I would like to see AFR get into the FE world as from what I've seen in the small block Ford world, they perform very well.

Sorry, I meant Trick Flow.

Just in general, middle of the road, average, combo of street & racing, low to high rpm....but if you must, on the street, 500-650 HP/TQ.
Ya know, best of all worlds.

With that criteria, I'd go with cammer heads.

With those criteria, if you have the funds, a set of Blair Patric pro ports would arguably be “the best”.

But I think if you look at the dyno section you will find that the Felony, BBM or trick flow heads are all capable of those numbers. The TF look to offer a bit more bang for the buck with the CNC porting, but they have their quirks.

I think most would agree that the BP PP heads are on another level and are worth the extra money.

There are others out there, the pro-max are not so cheep knock offs of edelbrocks, ( from what I’ve heard, and for the price you might as well just buy a set of the Edelbrocks.

Speaking of Edelbrock heads, out of the box you probably won’t get there, but with some work they have made some serious power.

Take a look at the dyno section and it should give you a pretty good idea of what heads will do what.

His PP cost seems to be a mystery, is it some tightly held number?

As always, question then becomes how much they'd help the combo at all.  Hard to beat TFS for a typical 445-462ci hydraulic roller'd deal.  I know PP's have made great power on combos that are a notch above this type engine, but at ~600hp you start looking at stock 2 bolt bottom end block survival, so not sure it's worth the expense bolting them on this type deal.  These 4.25" strokers in cheap blocks seem to hit a nice sweet spot for budget, RPM window, lowend torque, and hydraulic roller stability.

How much are Blair's pro ports ?

[frnkeore]

Blairs PP are more for the "competitor" and not the street/strip car.

They can go into the realm of the Johnny Horton song "North to Alaska" in the lyric "WAY UP NORTH", depending on valves, springs and attention to detail.

You should take a look at Jay's heads.

I must be a hybrid. Since I’m putting them on a mainly street/some strip car.
