combustion chamber design?

[my72vette454]

I dont know much about about chamber design and quench area to control detonation when using forced induction so I am wondering what to look for on a big block chevy as far as using open chamber heads vs closed chamber and the shape of the piston in relation to the chamber. As I understand it, open chamber heads will flow a little better because the valves are unshrouded a little more. Is a flat top piston better than a domed piston, assuming you can get the proper compression ratio with domed pistons? From what I have read, 8.5 to 1 ratio seems to be a good ratio for forced induction on the street/strip. Would love to hear some thoughts on the subject.



Thanks,
Mike
