I have read the article about intake and exhaust manifold instillation and there is section about cutting or trimming the metal gasket for the heat pocket area. I am using a 63' in/ex and i'm not sure if i should trim i the straight part of the bridge or cut it off completely?
Another question about the exhaust is the two out-most studs rub up against it (in the holes). Now.. i know the manifold should be "floating" sooo, should i hit the studs in-ward or grind the holes bigger or what? any help would be appreciated.

Sounds like your exhaust manifold is warped. You should get a new one, or at least a newer one. Try and get a later style with the round counterweight.

Don't hit the studs....they will snap off!

Take your gasket and lay it over the manifold and determine how much yours has warped. On mine it wasn't that far off so I ported the manifold to match. I also had mine surfaced flat and enlarged the outer holes a little so it would float. It has run for over 7 years with out problems.

I use Remflex or sometimes Corteco gaskets which do not require trimming. They seal very good with out any problems.

Actually those two studs broke off on removal so i had to drill out the old re-tap and heil-coil, which i think in the process they move out a bit (but they're at the right angle)

wow...actually it is warped a little.. well it looks that way from that gasket i have. Thanks for the heads up!!

In that case, I would follow Ted's advice and port-match the intake and exhaust manifolds to the gasket. If you are using the 63 exhaust manifold then you should trim the metal gasket between the intake and exhaust manifolds.

I also like Remflex gasket, but they are a bit pricey.

"If you are using the 63 exhaust manifold then you should trim the metal gasket between the intake and exhaust manifolds." would that be for the heat pocket part of the manifolds?

There is only one gasket that goes between the intake and exhaust manifolds. The one directly below the carb.

ok. cool, were on the same page!! thanks

If we bolted you to a head and blew exhaust gas through ya, you'd get warped, too!
