Contour Enthusiasts Group Archives Forums Modifications General Mods SVT Intake Manifold already Extrude honed!?

Dan,
I think you will find only one of the two intake ports on the head extrude honed,that is, the primary one with the injector,they may have done both on the 'late' returnless SVT's with the 10.25:1 CR,I'll pull an intake off a new SVT motor in the shop & check...but I know for sure on the pre returnless its only one port...
