I too have never seen one.

Thanks Rich and Kevin! I will ask the owner who is selling the entire motor if I can c.c. the heads and then I will report back if he is agreeable.

I'd say that 63 cc head is a mis-print. I've never seen or heard of a 441 head with 63 cc chamber. You might need to call tech dir in your div. OH! You would be able to SEE the difference between 63.3 and 73.26. Big difference.

I would double check with tech, but I have done several different small blocks that have bee n changed from 76cc to 63.3, 75 350 w/882's is one 73-74 350's w/993's is another one that has been changed.
Can spot it pretty easy takes about .150'' angle mill reduce them to 64cc.

On the 290 '68 head, which is set for 68.9 cc's, it takes .008" off of the deck to reduce chamber volume by 1 cc. A good original pair of those that I did years ago, in their original state, after de-carbonizing the chambers until they looked brand new with the original valves still intact, checked out to be 79 cc's. It took .080" off the deck to get them down. After using the right valves and equalizing the seats, they finished up at 69.5cc's.
Sometimes when doing a set of heads, they need to be assembled and checked with the final valves you are going to use several times. This is labor intensive, to be sure, and takes time. That is why the noted best cylinder head guys out there charge a bunch for a good set of stocker heads. After the cam of your choice is installed where the grinder tells you to put it, the piston to valve clearance has to be verified, the proper push rod length has to be ascertained,(remember that sometimes the intake and the exhaust optimal push rod length might be different between the intake and exhaust,) and then the issue of getting the intake to fit comes up. This is not work that can be rushed,every bit of it has to be checked, rechecked, corrected as necessary, and verified. If you enjoy this type of work, it can be rather rewarding to see the difference between an OEM engine and one built to Stock Eliminator specs and experience how it runs.Best wishes on you and your project!
