Cylinder Head Porting






Head porting is our #1 specialty and is second to NO ONE!!  We take a high tech approach to porting & designing a cylinder head port shape. The results are high flow levels, maximum port velocity, good wet flow, & strong swirl characteristics for maximum power & combustion efficiency. 

Even though we offer basic porting levels, each cylinder head is ported based on the whole combination.  Each component & spec of the engine & vehicle are considered.  We then use years of flow bench, track, & dyno proven port mods to give the best performance.

Check our article on CFM (Cubic Feet Per Minute) and how it applies to horsepower.

All our porting is highly developed on our Superflow 600 flow bench.  The Superflow 600 is equipped with a high tech swirl meter, velocity probes & other "advanced" port designing tools.  Every set of heads we modify are provided with flow data sheets.  The following porting levels are a general guideline to break down pricing.
