RHS Pro Elite LS3 CNC-Ported 6-Bolt Cylinder Heads

RHS Pro Elite LS3 CNC-ported 6-bolt cylinder heads utilize the popular LS 6-bolt head design to provide more clamping force for high-horsepower or boosted engine builds. This bolt pattern also makes Pro Elite heads compatible with the RHS LS race block, GM LSX block and OEM 4-bolt blocks by simply leaving the bolt holes at the top and bottom middle of the cylinders unused. These heads are available bare or assembled—along with a variety of other performance options.

Features:

* Increased clamping capacity over standard 4-bolt design improves head gasket retention
* CNC-machined intake and exhaust runners, as well as combustion chambers, increase airflow capability
* 0.660 in. and 0.700 in. lift valve spring assemblies allow for higher lift cams and increased engine RPM
* Designed for high-horsepower and boosted GM LS3 applications
