STD bore size pistons are not recommended in a used bore for any performance engine unless the bores have done minimal work with minimal wear and the correct piston to bore clearance can be adhered to.

All piston manufacturers have a specific piston to bore clearance that they recommend. If STD bore pistons are requested and there is a piston to bore clearance issue we will not exchange or refund, due to the reasons given above.
