thinking about getting a set or eq magnum heads or the new rhs heads....never ran a set of magnum style heads before. what would be a good piston to run with these heads to get around 9-9.5 compression??? been doing some studying but kinda confused on the whole quench thing...been looking at some kb pistons and it says u have to machine to get optimum quench?? don't wanna act dumb but never dealt with this quench stuff before....don't wanna do any more machining than i have to either
