Pro Elite#153 CNC-Port 6-Bolt Cylinder Heads for GM LS3 Engines use the LS 6-bolt head design, making them compatible with the RHS® LS Race Block, GM LSX Block and OEM 4-bolt blocks.


Increased clamping capacity over standard 4-bolt design improves head gasket retention
CNC-machined intake & exhaust runners as well as combustion chambers increase flow capability
.700” Lift dual valve spring assembly allows for higher lift cams and increased RPM
Designed for high horsepower and boosted GM LS3 applications

All RHS® cylinder heads feature patented Clean Cast Technology™, a revolutionary process that eliminates casting flaws and promotes a smoother internal surface finish for greater air and coolant flow. These benefits provide more power and cooling, right out of the box.
