Full Port Job, Tapered Nose Bronze Valve Guides, Stage 2 High Lift Valve Springs, Stainless Steel Valves, Assembled
Pricing: $1,895.00


MHS Stage 2 2V NPI Cylinder Heads 

We take stock seasoned NPI head cores, port to our Stage 2 specs, and install our custom tapered nose manganese bronze guides with ultra tight valve stem to guide clearances to improve both oil control and allow an improved performance valve job to be done.  The stock head has double to triple the valve guide clearance and thus you have to make the valve job much lower performing.  0.5mm oversized custom stainless steel valves are used to increase the flow.  We then go from the stock 2 angle valve job to a performance 5 angle which includes tightening of some of the angles and widening of the others to enhance the flow.  Heads also include performance aftermarket valve springs.
