These heads offer superior flow characteristics and are available with either a 320cc or 360cc intake runner. They are cast, machined and assembled with great features such as multi-angled intake seats and radiused exhaust valve seats, revised water jackets for better thermal conductivity for reduced chance of detonation, thick deck surfaces, hardened exhaust valve seat, manganese intake and bronze exhaust valve guides. These heads also have a 119 cc chamber volume that is “compression friendly” for street or marine applications.
Part numbers for the new Big Block Chevy heads are CH454A for 320cc intake runner and CH454B for the 360cc intake runner. For more information about the EQ Big Block Chevy cylinder heads or any of their products, visit http://www.aamidwest.com/
