396 Chevy BB

[djfish55]

Have 1968, 396 BBC also have set of large oval port open chamber heads to put on engine. Engine originally had closed chamber heads. I want pistons that will provide 10:1 compression or better. Engine has been bored .030. Is any thing available for this combination?

I have a set of 67 closed chamber heads for that.

Keep an eye out on the CC size of the head chambers. If you use a head that has been milled and changes the cc of your combustion area you will kiss that 10:1 ratio good bye.
