Machining is performed by hand using a Peg grinder micrometer-fed, electric valve seat grinder. This machine oscillates about a vertical shaft and is fed into the valve seat with a micrometer feed on the top of this shaft. It allows for almost an infinite number of angles to be employed since the stones used are shaped and trued on the power head to a user defined shape or angle. Each angle is cut separately unlike the Sunnen or Serdi that cut all (usually three) angles at once. This requires significant operator skill so we use one of the best "superbike" head builders in the business. We also use this equipment to determine proper cutter angles for Sunnen valve seat cutter to reduce cost for the more common valve seat angle combinations.
Noticeable power increases across the entire power range correlate directly to improved sealing and flow.
