BBC 12° Spread Port Cylinder Heads
Race Winning Performance out of the box...

• Pro-Stock Port Design promotes high intake port velocity

• 60cc Combustion Chambers allow lighter pistons, more compression and better combustion

• 12 Degree Hi-Flow Valve Angle Design

Power... We're Talking Serious Power!

That is what you get with HITMAN BBC Spread Port Cylinder Heads. Designed with a 12 degree intake valve angle, you have a lighter piston and smaller chamber resulting in better combustion.

The HITMAN 12 degree Big Block Chevy Spread Port Head takes the guess out of finding the right port for the best power. Based on our Pro-Stock port technology, our out-of-the-box port design provides better airflow than competitors larger CNC port designs, and that means INSTANT HORSEPOWER!

The HITMAN BBC Spread Port Cylinder Head has what it takes to win: 12 Degree valve angle, Spread Intake Ports, Reliable Hi-RPM Valve Train configuration, efficient intake ports, efficient combustion chamber, high-quality castings and much more.

Notes: 1) Intake Valve: 2.400 2) Exhaust Valve: 1.900 3) Flowed @ 28in of water
