Streetable Intake Porting and Side Housing Resurfacing Services by Racing Beat - Racing Beat offers both our resurfacing and intake porting services as a convenience to our customers. Price includes porting labor and resurfacing charges for all three housings. Read details regarding these services as follows:

Streetable Intake and Exhaust Porting (all models except 6-port intakes) involves changing the size, shape, position, and surface finish of the ports and port runners. The power increase from porting varies, depending on the other modifications made to the engine, but averages 20 percent. Low-RPM torque is reduced slightly, but idle is still smooth. Intake porting includes two primary and two secondary ports.

Side Housing Resurfacing (Lapping) - When rebuilding your engine it is highly recommended that you resurface the side housings if the level of wear permits. We recommend removing no more than .002-inch of material from each side of the 1986-95 housing surfaces to maintain the integrity of the O-ring grooves. With the 1971-85 housings we can remove material to the following minimum thicknesses: Front Housing 1.568-inch; Intermediate Housing 1.955-inch; Rear Housing 2.355-inch.

Our resurfacing process utilizes a lapping table and an optical-grade polishing compound to produce a surface finish that exceeds even the factory finish. The superiority of this lapping process well exceeds what is generally available through surface grinding operations.

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.
