These LS Cathedral Port heads are engineered with the same architecture as the factory head, and all stock components will fit without issue. RHS® Pro Action™ LS Cathedral Port cylinder heads are manufactured with premium materials and machined to the industry’s tightest tolerances. They feature premium bronze/manganese valve guides for long wear with particular emphasis placed on holding precision tolerances on valve seat concentricity, which allows the valves to seal securely for more power.

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. A unique dual seat spark plug pocket design allows you to use both the factory style tapered seat spark plugs and also flat seat style plugs that are available in wider heat ranges for high performance applications.

RHS® Pro Action™ LS Cathedral Port cylinder heads are designed for any high performance or stock application and offer one of the best performance values for aftermarket GM LS Cathedral Port heads.

Assembled head includes: dual valve springs, chromemoly steel retainers, heavy-duty stainless steel valves and valve seals.
