CNC Ported Cylinder Heads...BIG FLOW for BIG POWER custom machined to your needs!

How are we different?
You want flow? All of our cylinder heads have been developed on the flow bench and dyno paying attention to critical details of flow, turbulence, and velocity. Each head is flow tested and comes with a chart from a SuperFlow 600. Whether it is our big flowing K-Series heads or our new GSR and H22 programs, you will be sure you are getting the most from your engine and doing it with a beautiful product.

What about turnaround time? We have heard of shops taking months and some over a year to complete a cylinder head!! We can give you a completed cylinder head in a matter of days! We will never have a cylinder head for more than 2 weeks and have the capability to turn one around in ONE DAY start to finish! That includes seats, guides, porting, surface, valve job, ready to ship!

How is the quality? While other head developers are out price shopping to find the cheapest CNC machinist to maximize profits, we went straight to the experts...to the inventors of CNC Cylinder Head Porting. Our heads are precision machined on state-of-the-art CNC equipment by Weld Tech in Brownsburg, IN. www.weldtech.com

Look close and you can see the difference. Our designs aren't just hogged out conventional head porting. Every bump and dip is there for a reason...to move the air where we want it.
