How much do you want to spend? The stinkin Speed Pros are around $350 for a set. They are pretty heavy, but strong. A set of SRP's are around $500. They are a high silicon content piston which is good for street use. A forged JE is around $600. Theres plenty of other pistons out there that will make better power than any of these, but we need to know whats in the budget.

To get 10.5:1 with a flattop youre gonna have to mow your heads down to around 54cc, depending on the valve relief size.
