Fast Burn Aluminum SBC Head

New and improved from Chevrolet Performance is the latest version of the Fast Burn aluminum heads for GEN1 Small Block Chevy engines. Updated castings for improved air flow and performance now include LS-style beehive springs that provide the ultimate technology for superior valvetrain control to match today's performance camshaft grinds. These unique performance heads have dual valve cover bolt patterns for the center bolt and perimeter bolt designs to allow an array of choices to meet your requirements. The Chevrolet engineers designed the "Fast Burn" combustion chamber for superior combustion efficiency that maximizes the air/fuel mixture for increased torque and power. The large 210cc intake port provides a broad torque curve to meet most any requirements for a Small Block performance engine build. SDPC suggest the Vortec intake manifolds for proper port alignment.
