That is the last 3 digits of the casting numbers. They are factory GM iron oval port heads, open chamber. "781" heads are decent flowing heads, must have some domed pistons in it to achieve 10.5:1 CR with those heads. They have about 119 cc chambers.

Thanks Jim, I appreciate the info. Your 70 is very nice, hope you have fun with it. Hope my 69 turns out as nice as yours.

Thanks for the compliment. Good luck with your project and have fun!
