piton size

[notsed]

so the skirt broke off, the bore was loose. the #rs on the piston ends in 6450 im assuming this means 50 over but i want to make sure i order the right size. the cylinders are in good shape, so whats the next closest size up 64 75? also are the wiesco pro lites worth the money for the power gain? its goin in for port work also moderate drag port

 

any info would be great

64.75 is good if you're at 64.50 & Wiseco Prolites is as good as it gets. Grab yourself a digital caliper!
