Stage II CNC Head Work

$999.00

Our Stage II headwork is a complex blend of CNC porting & hand blending. First your heads are disassembled, cleaned & cut in our state of the art 5 axis CNC machines. Once they have finished the CNC porting programs the valve seats are blended with the ports & combustion chambers. New valve guides are installed along with new valves then toped off with a high flowing full radius valve job. Valve to valve clearance is set for your cam.
Combustion chamber volume is measured and the heads are surfaced for your desired compression.
Cylinder heads are cleaned and new valve guide seals installed. New spring packs with chromoly retainers are installed & set for the cam being used.
This head package will greatly improve your engines efficiency, breathing and will deliver professional results that you can only get from R&R Cycles.

Additional cost of $124.00 for Titanium retainers.
