Don't bother searching through junkyards for 243 or 799 casting heads, the RHS Pro Action LS1 Cylinder Head is a better option. Manufactured from premium materials to the industry's tightest tolerances, the RHS Pro Action Cathedral Port Head for GM LS1/LS2/LS6 is a far better option. Compatible with stock components along with COMP Cams premium valvetrain components, the RHS Pro Action Head is ready to bolt on, requiring no milling or clean up like junkyard pieces. Available bare, un-assembled for porting projects as well as pre-assembled, the RHS Pro Action LS1 Cathedral PortCylinder Head is a great choice for your next 4.8, 5.3, 5.7, 6.0 and 6.2 GM LS project!
