Precision Race Components 225cc As-Cast Aftermarket Casting Heads & Cam Package

The all new PRC 225cc As-Cast cylinder heads are available for customers looking for the ultimate as-cast cathedral LS heads. The new PRC as-cast intake port has been flow-bench tested to flow over 320 CFM and can support everything from smaller camshaft street engines all the way to all-out race engines. This cylinder head is a combination of a max-effort, high-flowing port with a smaller chamber designed for max power in stock cube applications. You have your choice of the 62cc chambers used in the PRC 227cc cylinder heads or the 68cc chambers used in the PRC 237cc cylinder heads. We can mill additionally to get to your desired chamber size for no additional charge! These are the same cylinder heads that were originally used on The Cutty from Discovery's Street Outlaws that produced 1,400 RWHP using a single turbo system and a GM 6.0L iron block! ***If you purchase a Melling oil pump you MUST use a single-roller timing set! The Melling oil pump will not clear a double-roller timing set!***
