What Edelbrock Heads to use

Do the pistons stick out of the deck and are you building for quench?

The 60179 head you could always mill to get rid of/reduce the recessed area of the head. That's what I did with one set.

All depends on what you have and how it all fits, and you goals in design.

You aren't going to notice a .2 change in compression either.

The 60179 deck looks like the old X/J/O heads, with the combustion chamber stepped into the head because the stock pistons stuck out of the bore. 60779 has a flat deck
