FAQ
Are these pistons drop-in?They’re supplied with rings, pins, and clips for an OE-style install, but precise measurements and machining checks are required to verify clearances.
When do I need .100" valve reliefs?Choose valve reliefs if you run a high-lift cam, tight piston-to-valve clearances, or aggressive timing—especially in high-RPM use.
What coatings are used?Performance crown and skirt coatings help manage heat and reduce scuffing under heavy load and high EGT.
What supporting mods are recommended?Head studs, correct head gaskets, a strong fuel system, and (for LML) a CP3 conversion if you’re increasing fueling/power significantly.
