Yes. Just because the casting number is the same, it does not mean the casting itself is the same. There are several known versions of the 441 head in particular.

Re: Stock Eliminator Heads 441 question
 

The specs that are listed in the NHRA guides may or may not be what was actually produced by the auto maker (all brands). The specs listed are the specs that NHRA Tech Department chooses to accept and publish as "NHRA's Accepted Specification". The acceptance process is usually done by what the auto maker submits to NHRA as the spec for specific engines. I believe NHRA has also altered some specs by what their Tech inspectors suggest or another long NHRA process. In short, What is published in NHRA specs may never be found in a junkyard or stack of engines. On the other hand you may find parts with the NHRA specs.

Thanks Adger and Alan. This information makes picking used heads even a bit more difficult. I will have to cc all heads as I am sure I will not be able to tell the difference between a 63 and a 74 cc chamber volume! Any tips on selecting used 441 castings?

Re: Stock Eliminator Heads 441 question
 

I never saw a 441 head with anything but the large mid 70's CC chambers...

They were usually 75-76 cc's or a little larger, unmilled......

1.94-1.5 valves and there were some with 1.6 exhausts used on I believe 1970ish 400's in trucks with 3/8ths valve stems.....IIRC....

If they made a small CC version, I never saw one....

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.
