Edelbrock Performer RPM heads
Edelbrock Victor Jr single plane intake
5.0 Ford block
Victor Rienz intake gaskets.

With the intake setting on the heads and studs screwed into the heads (where intake bolts normally go), the bolt holes in the intake match up to the bolt holes in the head very well. I started with the intake setting with the studs centered in the holes. When looking into the #3 & #4 ports, through the open carb flange you see the edge of the front of the ports flanges. If you slide the intake back as far as it will go (against the studs), the passenger side looked ok, but then the back edge of the ports flanges shows on the drivers side #6 & #7.

Centering the intake gaskets to the bolt holes in the heads, the head ports match up to the gasket fairly well, with the exception of the head ports having been opened up about 0.010" bigger than the gaskets (by feel - I didn't measure this).

When centering the intake gaskets to the bolt holes, on the drivers side of the intake manifold flange, the drivers side ports are centered with the gasket, with the exception of #7. The #7 is out of center to the rear by 0.020".

When centering the intake gaskets to the bolt holes, on the passenger side of the intake manifold flange, all ports are off center with gasket. All ports are off center to the front of the engine. Each port gets progressively worse, with #4 being 0.065" off and #1 being 0.090" off. So there is flange showing on one side of the port and on the other side of that port the gasket is into the port opening (covering part of the port).

If I were to grind the ports out to match the gasket, then those ports will be wider than the rest and the gasket will hang into the flow on the other side. I am concerned about getting flows screwed up, as this intake was modified by Mass Flow and now has fuel injectors at each port. So equal flow is important with EFI.

This truely sucks! How much Hp will it cost to leave it as is? What would you do?
