We offer precision CNC-porting to achieve optimal air/fuel flow and velocity. In addition to the headwork we also include a Leading Edge high-lift proprietary valve spring set that is stable under the increased horsepower and torque of out LE kits. We also install manganese bronze alloy valve guides as well as grind the stock valves to our exacting standards. No Refunds or Exchanges on our porting services.
HEAD PORTING IS SUBJECT TO A 2-8 WEEK WAIT AFTER YOUR CORES ARE SENT AND RECEIVED.
