460/429 head question
In looking for an older set of heads (68-72) for my 429 do they need to be from another 429 or can they be off of a 460 as well?
Please don't pull out in front of me! I can't afford to play "What's this?" with you or your car.

Try for the D0VE-A Heads off a 70,429
If not the C9VE heads are okay.

'68-71 429/460 Ford/Lincoln heads, with the exception of the CJ, are, for all practical purposes, identical.
In '72, Ford went to a larger combustion chamber, smog bump in the exhaust port and different rocker arm configuration.
bigred78 is right about there being lots of heads on ebay, but be careful as auction fever creates some crazy prices. And it costs about $80 to ship a set of 385 series heads.

George,
Are these heads usable for a CR low enough to use low octane gas?
Thanks, Ron

460/429 head question
If you use the early, small combustion chamber heads, you'll need to use pistons with a lower compression height to lower the c/r from 10.5-11.0:1 that results with stock, flattop 429 pistons. The piston selection for 429s is tiny compared to the 460.
This discussion has been addressed in prior posts. If you're not replacing the stock pistons in your rebuild, you can't use early heads and run low-octane gas. If you're going to use new pistons, you'll be better off spending $150 for a 460 crank as the 460 has a wide selection of pistons that will give you whatever c/r you need. All that's different between the 460 and 429 is pistons and crank.

460/429 head question
Sorry, I guess when I asked the question, I didn't realize I was asking about the 429. I meant to ask the question concerning the use of the earlier heads to build a 460. I want to build a 460 to use in my truck to tow my trailer and if possible, still be able to use the lower octane gas. So based on what you said, if I use the right pistons, I can use the C9VE or D0VE heads and still keep the CR down for what I would like to do?
I'll look for the other posts concerning this.
Thanks again, Ron
