These BB-2 Xtra cylinder heads from Brodix Cylinder Heads flow over 375 cfm with only the bowls blended and the intake ports matched to the gaskets. The intake ports have been contoured and matched for use in today's 540 cu. in. or larger bracket-racing big block Chevy engines. These cylinder heads will accept all standard pistons, intake manifolds, and rocker arms, and the valve cover rails are raised to prevent leakage. They're available in both as-cast and CNC-ported versions.
