Show original supplier description
The PRC As-Cast 225cc LS1/LS2 Cathedral Heads from Precision Race Components are engineered to deliver high flow and performance for LS1 and LS2 engine applications. Constructed from as-cast aluminum and proudly made, cast, and machined in the USA, these heads feature 225cc intake runners that have been flow bench tested to exceed 320cfm, supporting a wide range of builds from street engines to all-out race configurations. These cathedral port heads offer a combination of a max-effort, high-flowing port with smaller chamber options for maximum power in stock cube applications. You can choose between 62cc or 68cc CNC-machined chambers, which can also be milled to your desired size at no additional cost. The heads come equipped with 2.06" intake and 1.600" stainless steel valves, and they utilize factory LS1 rocker arms. Additionally, they include a TSP Dual Spring Kit with PAC .660" valve springs, with options for hollow-stem intake valves to save approximately 15 grams. These cylinder heads are designed for LS1/LS2 applications, with specific configurations available for small bore applications (maintaining good piston-to-valve clearance) and large bore applications suitable for stroker or boost setups.
