FAQ
Are these “drop-in” without machine work?As a standard-bore kit, many rebuilds are drop-in, but you must confirm cylinder condition and clearances. If out of spec, hone/bore as needed or choose an oversize kit.
What’s the difference between Stock, Performance (CC), and Race (FCC) kits?Stock = no coatings; Performance (CC) = coated crown & skirt + chamfered tops (this product); Race (FCC) = CC features plus .100" fly-cut valve reliefs for high-lift cams.
Do these include rings and pins?Yes—each kit includes matched rings, wrist pins, and clips.
Which ring sets should I order if I need extras?Order six single-cylinder ring packs that match your bore size (STD, .020, .040). See our 12V Pistons & Rings section.
Should I add head studs?For towing or higher boost, head studs are strongly recommended for clamping strength and gasket life.
