FAQ
Do these pistons drop in without machining?No. They are .020" oversize and require a precise overbore/hone and clearance verification.
Are valve reliefs required?Not for stock cams. High-lift aftermarket cams or tight piston protrusion may benefit from fly-cut reliefs for added piston-to-valve clearance.
What coatings are used?A thermal barrier crown coating helps manage heat, while a skirt coating reduces friction and scuffing under high load.
What supporting mods do you recommend?Head studs, correct head gaskets, adequate fuel supply, and careful tuning. Consider upgraded valve springs/retainers with big cams.
