Race Exhaust Porting (All engines) - Race Exhaust Porting is a modification performed only on a new rotor housing as provided by the customer or Racing Beat.

Either Blocking Nozzles (for 1975 and earlier housings - see Engine section) or Air Injection Hole Plugging (for 1976 and later housings - see Engine-Services section) is recommended, but not included.

These services are performed at Racing Beat's production facility in Anaheim, California. Prices listed are for labor charges only. Return shipment freight charges are not included in the listed price.
