Increase Head CC's
I don't get it.
With a 4.06 bore, 4" stroke, 60cc head chamber, 13cc of piston dish and valve relief, .039 gasket with a 4.18 gasket bore (Felpro 1008) and a 0 deck, I get 11.38:1 SCR. If you're shooting for 11.3-11.5 I don't see why you need to change your CC volume at all? Build it with the 13cc piston and you're golden. The dish on the Icon's doesn't really give up any quench since the resulting shape is basically a stepped piston like the KB356.
