8hspace.gif (810 bytes)These are heads that would have been used in Camaros as either standard or replacement during the period. There were other heads used in Chevrolet engines which may have ended up on your motor if it's not original. If you do have a head with a number not listed here, you can find it in "Chevrolet By The Numbers" by Alan Colvin. Find out where to get it on the books page.
