The porting process preformed uses a new 5 Axis CNC Cylinder Head Porting Machine with CAD/CAM software specifically designed for cylinder head porting. CNC porting brings unparalleled accuracy to head porting with each port flowing the same. This helps balance the power that each cylinder produces, making tuning easier. After the CNC process we then hand blend each port to perfection.

New Custom port Oversized 36mm Stainless Steel Valves:
We use the highest quality upgraded stainless steel valves with a nitrate coating for ultimate durability to out-perform and outlast any aftermarket or OE valves available.
- NOTE: Because of the larger sized valves in this head they will not clear a 5.9 bore. You must have at least a 4.125 bore to clear.
High Strength Alloy Valve Guides:
New High Strength Alloy, Heat Treated iron based valve guides are installed. These guides are heat treated to Rockwell 22 C Scale, which produces the ultimate in wear resistance. This is far superior to original guide material, including Bronze. The guide incorporates a spiral grove inside the guide to hold oil and aid the lubrication of the valve during engine operation.
High Temp Valve Seats:
Premium valve seat inserts made from a true Nickel Based Non-Magnetic material that was developed for extreme operating conditions. These valve seats immensely reduce the possibility or dropping a valve seat.
Drilled & Tapped Coolant Freeze Plugs In Head:
The factory head has press in freeze plugs that are prone to leaking and blowing out under the valve cover. This process eliminates the failure from ever happening to you with our cylinder heads. We use high quality steel plugs where others use aluminum that are prone to leak.
Fire Ringed Head:
The fire ringed head procedure was designed to use with our custom fire ring head gasket which utilizes a radius cut steel fire ring to virtually eliminate head gasket failures while still allowing you to daily drive your vehicle with confidence in its longevity capabilities.
Valve Springs:
We use the highest quality brand new 120lb valves springs custom made right here in the USA. We designed these springs to offer more lift than the competition. Each valve spring is tested multiple times in house before assembly to ensure it maintains it proper spring rate.
