RPM air Gap problems?

Hey:

I didn't use cork gaskets (not sure where that came from). I used Edelbrock gaskets. They are similar in construction to the Fel Pro, but I find the port match on the heads is a lot closer. The edelbrock stuff seems to resist crushing a little better.

My method for checking was to line the gasket up on the head, torque the intake to spec, etch the protruding part of the gasket with an awl, remove intake, and then line up the intake with the awl marks on the gasket. In this way I am sure that I'm seeing where the ports on the gasket really are when the thing is bolted together. I can't see how your method (as described) would give any real indication of what is going on when its all together, and there's not anywhere near enough adjustability in the position of the intake to correct the fact that the ports aren't in the right place.

As for my experience, I can't see how that Pro Products POS could line up with any mopar head correctly.


I just lined up the gaskets on the heads & checked the allignment, then i layed them over on that side of the intake & checked there, it looked pretty good, now how well you center the intake on the head is another story when you button it up lol. On my BBs, i check the upper & underside F&R of the runners with a feeler gauge, but thats hard to do on the SB intake.

I can't speak for the Iron Ram heads (i'm running RHSs), even though the runners seem alittle smaller on the crosswind, the allignment wasn't bad, now i also noticed in your article on this intake you were useing a cork gasket like an LA one, my Magnum gaskets were alot different then the ones you posted, i bought the felpro magnum head set FEL HS9898PT1 & those intake gaskets were nice, had a film coating & rings around the ports, not just a flat peice of cork, did you slot a set of LA intake gaskets to fit the Magnum heads?
