Mahle piston valve reliefs I am building my budget engine for boost & I am using -4cc mahle pistons. Is it a good idea to round the sharp edges on the valve reliefs to deter knock? Has anyone done this?
Thanks,

Mahle's PowerPak piston assemblies include forged pistons, piston rings, pins, and wire locks--all in one race-proven package. The pistons are hand-deburred, and then coated with dry phosphate to protect against ring micro-welding and pin galling during initial startup. For additional performance, Mahle added its proprietary Grafal anti-friction coating to the piston skirts. Low drag rings, steel pins, and round wire locks complete the Mahle PowerPak package.
