long time lurker, first time poster :)
i picked up this set of C2 heads last weekend. Bought them because i had been looking for a small chamber head and these had been ported and had CJ sized valves installed already. didn't pay much attention to the HM stamp on the front pad. got home and noticed the C2HM line along the bottom of front pad on both heads. posted in a couple places, had some feedback that they're probably legit. where i'm striking out, is there anyone that can help me find out more information on them? possibly what the rest of the C2HM stamped line means?
thanks guys!

HM sold "performance" cylinder heads back then and the limit was the thickness of your wallet. LOL These look legit and were good "for the day" . More recent heads ( HR , MR , TP , 428CJ) are better . The nice thing about these is the work is "undetectable" when bolted on plus the "cool factor" of being from HM.
Nice score.

Be interesting to get them on a flow bench. Neat Find!

68montclair (Zack), Great find I am sure Jason would put them on his flow bench.

Feel a little guilty, bought em to throw on a 390 i have laying around that i want to put in a foxbody. Might have to pull the edelbrocks off my montclair and put them on the fox instead lol

I wonder what ever happened to the Dr. on the old network 54 Forum..I believe he was C5HM....His knowledge would really be helpful...
None the less.....cool set of heads..

Doc is still around, but if you don't recall, he lost several of his restored vehicles to flooding. Pretty sure he was able to save at least one, but still, that had to be heartbreaking to lose those cool cars. I wonder what the insurance company did with them.

C5HM ( Dr John Craft) is still around as cjshaker mentioned. He is a great "factual" source for all things Holman Moody. By factual I mean he knows the difference between "Ford" parts , Ford parts "sold" by H&M , and "H&M" parts as well as THE cars they built.

Does anyone have any contact info on him?
Since 1968, I have had a H&M marked (part #), dry sump system for a 289. It came out of a McLaren MK4, Can Am car. I've never seen another one.

Frank ,
Was the McLaren purple by chance?

will the valves on those heads clear the cylinder walls on a 390 without notching the cylinder walls?
thanks for the feedback!

Randy, I don't know the color. His name is Kurt Speet, he raced in the Mid West.
I was wrong about the year I bought it, it had to be '70 and I was wrong about the MK4, it was a MK3. I confused it with the Atlantic Mk4. It was a long time back.
This is the car, he took the Ford out and put a SBC in it and only race a couple more times, after that, last time in TX, I think.

Dr. John Craft is on Facebook as “Jac HMguy”. You could probably message him there if you’re on Facebook. He saw these heads on 68Montclair’s Facebook post and commented there.

Thank you, Kevin.
I'll go look for him.

I would have those heads cleaned and magged, then flow a port or two and see what they do. I don't expect a lot, looks more like they did more port than bowl work, but it would be nice to see them with some valves out.
In fact, you could wash them down with a garden hose and flow a port or two for laughs.
Cool find!
-
Last time I called HM (They have a website) the guy that answered told me he answers when the "boys" are out in the shop.
Give em a call, they probably have the answers to your questions.
-
Not HM heads but I have a set of heads with stamped numbers. I showed them to a couple of FE guru's, they said these were likely over the counter heads.
-
Chris ,
"My" experience tells me different. The $88 is a serial number from a "run" of heads. The casting number may be different than the number on the end of the head which would indicate some form of different machining was done to that "run " of heads. To verify that a side by side comparison would be needed. It could be anything from a valve size to an added or removed bolt hole. ALL things at Ford had to be documented and this head is one of those deals. I have had 351W heads done the same way.

The stamped numbers on the end of the heads appear to be a part number for a head assembly with the 6049 vs the casting number being 6090.The HM marked heads appear to be consistent with other Holman Moody parts in that they used Ford style part numbers with the HM in the prefix number ,the A in between the 6 and 0 in 6049 is consistent with some Ford part numbers.The heads appear to be 390HP or 406 heads that H/M performed some sort of upgrade such as porting or different valves or different valve springs and assigned a new H/M part number to.
-
I had two sets of Tunnel Port heads that were Holman Moody stamped but they had HM done with a proper letter punch not a prick punch. That would be 1967-68 era . I dunno, maybe in earlier times they did it a cruder way.
-
If you look at the upper left corner of the pic you will see a smaller HM stamp with a regular stamp with diagonal off set,I'm not sure what the center punch stuff is about.
-
Lee Holman still runs the business and has a few old timers working there with him. They are about 30 minutes from where I live. I’m sure if you reach out to Lee he may be able to give you some information about the heads.

Lance I've seen them like that and also (h with the letters joined. HM was one of a VERY

few entities outside of Ford that could fully machine raw castings ."Dots" with a center punch is not their style

Yes, my cammer block has "6HM XXX" stampings similar in style to the one in Lance's picture.

I really didn't pay too much attention to the dots I looked at the first pic wiith the diagonal offset HM stamp in the upper left and the C2HM part number below looks consistent with other HM stamped stuff I've had or seen.

John, he was referring to the MK3 McLaren, that my dry sump came out of. See picture on page 1.

He dumped his Facebook recently, miss his posts.

Mine had stamps like that and one pair had the holes in one end for a water crossover. According to the seller at Cilumbis Ford Expo 86 swap meet the heads were used on David Pearson's Torino with a box intake that had nbo crossover. I didn't get the intake but silly me in not asking about it's availability of ithe intake. Years later when i bought some pentroof valve covers with weird air fittings I never asked and missed the whole 68 Championship winning Nascar Torino that was run at Evergreen Speedway in the 70's.
