These Brodix Cylinder Heads BB-2 Plus heads work well with a heavy car and a smaller engine. The intake ports flow over 340 cfm with only the bowls blended and the intake ports matched to the gaskets. The combustion chambers are properly shaped for use with either methanol or gasoline, preventing detonation. These cylinder heads accept all standard pistons, intake manifolds, and rocker arms, and the valve cover rails are now raised to prevent oil leakage.
