'77 is for domed top pistons, I think it was '80 where they went with flat top pistons. You'll get horribly low compression with a '77 head on a later block, unless you use the domed top pistons or shave the snot out of it.

Right, flat top pistons are used with the smaller combustion chamber heads.
I have been told that you need to cut the mating surface of the head to the block. I was wondering if there is anyone out there, who has done this, and what they had run into.
Thanks for all the help.
