JEGS Small Block Chevy Cylinder Heads

Product images may differ from actual product appearance.

Racing technology for your high performance street engine! Our small block Chevy cylinder heads are cast from Virgin A356 Aluminum and heat treated to a T6 Hardness for the ultimate quality and durability. They are then machined on the latest CNC machines for accuracy and precision. We use the most up to date technology to design our intake and exhaust runners and combustion chambers for maximum performance. Our choices of intake runner volumes, combustion chamber sizes, spark plug styles and valve spring sizes insure that we have a cylinder head to suit your needs. Our cylinder heads are assembled with premium parts such as manganese valve guides, stainless steel valves and chrome-moly retainers. They feature valve seats that are compatible with unleaded fuel and also accept both standard and center bolt valve covers.
