Brodix BB-2X Aluminum Chev BB Head
The BB-2X head works well with a light car or large engine (509-555 cu in). It has a 340 intake port and flows over 360cfm with only the bowls blended and the intake ports matched to the gasket. These cylinder heads accept all standard pistons, intake manifolds, and rocker arms. The exhaust ports are raised .600" higher than stock. Valve cover rails are raised to assure no oil leakage. Assemblies include 2.300"/1.880" stainless steel valves, roller springs, 10 degree retainers and locks, rocker studs and guide plates.
