RPE Engine Refresh #12

Trial fitted the new Extreme Engines cams and adjusted the cam lash. Set the valve lash on the inlet cam to 0.008" and the exhaust cam to 0.010". Used various shims and recorded the size of shim and gap for each valve. 

Found on the inlet that 8 thou was inbetween two shim sizes and could get 0.007" or 0.009" but not 0.008". In the end I decided to go with 0.009" as there will be expansion when the engine is running.
