I appreciate all the input. I already own a set of bare nos heads. This for a 4wd f100 that spends some quality time off road. More power is always good, but it can’t be at the expense of my low end torque.

The heads from Carpenter are new old stock from South America.. Trevor says he wants them for a truck, not for high perfomance, so he's not into thousands for Mummert heads etc..

Those are pretty mundane heads that Carpenter has.

What do you want this engine to do? Be dependable or go fast? If you want to go fast look at the Mummert aluminum heads. If you are thinking of sourcing and buying good new old stock heads you will probably pay enough to make the aluminum heads worth the money. And they are something around 50 horse power bolt on's. There are several engine builders on this site like John Mummert, Ted Eaton and Timmy McMasters than can do an engine to whatever standard you want.

Thanks for the help. I suspect I’ll end up having the nos head built up to satisfy my ocd. At least I’ll know where they have been.

The C3TZ heads will be closest to original for the '64.  They aren't anything great but they are new and will match, so that is a benefit.  You can easily have a grand in parts and machining getting those heads ready to bolt on, though - check with local machine shops for labor and use Mummert's site or others to price parts.

The C0 and C1 heads are close enough that they should work ok together, though not ideal.  Many engines have been running with mismatched heads.

Here’s the link to Mummert’s site with the head casting info. There’s way more info on his site, so check the whole thing out.

OK, there has been a new troubling development.  I started taking off the intake manifold and realized the engine i purchased has mismatched heads. One side is the C1TE that i expected to find.  The other is marked COAE.  It looks like these may have different compression ratios.  I'm assuming these are not compatible.  My other option is a set of NOS heads i have been sitting on for years.  They are not marked externally on the head but have ct3z 6049-fg marked near the pushrod holes. Any thoughts?

Thanks, that is great advice.  The grade 8 bolts will be any easy swap for me.  I was planning on getting Mummerts upgraded head gaskets.  I was on the fence about having the heads milled, but the thicker gasket may have just made that decision easier.
