  • We all know a motor is an airpump, it takes a Head with good Airflow backed with good Velocity! You need X amount of Air with X amount of Compression and X amount of camshaft to make a certain amount of HP.  Airflow is extremely important, if you want more power you must increase the airflow demand into the motor to achieve more hp.. increasing velocity alone will not build the big Hp and TQ numbers you are after.   And our heads Deliver ! No fancy cross talk about math and formulas , WE have the tools required to do the research and the answers when you ask !!  If you want to build power, what your are lookin for is right here ! WE KNOW what it takes to build power and can help you with the parts you need to achieve your goal.


All heads come with Dual Decompressor ports for super easy starting.

Billet heads are available in 4 configurations.

Stage 1-

  •  Heads come set up with a 1.90 Intake valve giving 265 cfm  @ .650 lift rated in 28" of depression. A stock shovel head flows roughly 194cfm.  You are gaining almost 70cfm over stock! This head can support 100+ hp in a 93" motor with 256 degrees cam timing and 11.1 compression.  This head is intended as a drop on replacement and will work with most exhisting cam profiles.  This head is recommended for most applications.

  •  A properly built 80" with 256 cam timing and 11.1 compression and a 44mm carb and good exhaust should be able to hit 95+hp.

Stage 2-

  •  Heads come set up with a 1.94 valve giving you 275cfm at .650 lift.  This head is moving some real air and will make some real topend horsepower numbers. On smaller motors with a shorter stroke look for a camshaft with a tighter lobe seperation for best power.

  •  With A Stage2 head your allowing more air and your motor will reward you with more ponies at the rear tire! These heads love an Evo based camshaft with high lift and quick ramps.
