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 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.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 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.Performance 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 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.
