  • Solution clean head and inspect valve seats and guides and replace as necessary (NOTE: valve seat and guide parts and replacement labor additional cost).
  • Professional valve seat cutting using state of the art NEWEN CNC valve seat cutting machine. This step is absolutely required for quality results and the durability of your valves and yet is often overlooked by inferior service shops.

  • Provide contact information and order number in the package with your head
  • Allow 3-6 business days for this service to be performed
  • Once completed we'll send your head back to you
