Stage 1 Ported 2V NPI Cylinder Heads

Full Port Job, Tapered Nose Bronze Valve Guides, Assembled
Pricing: $1,495.00


MHS Stage 1 2V NPI Cylinder Heads 

We take stock seasoned NPI head cores, port to our Stage 2 specs, and install our custom 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.  To keep the budget down we reuse the stock valves and springs with the Stage 1 head.  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.
