need 292 exh man gasket help
 

Looking for info on what kind of gasket to use on my 292 exhaust manifold. I replaced it once with one from napa, and it didn't last very long and im tired of the ticking. Need info on what to use. Maybe its warped. I need to get it off again and inspect it.

Are all the exhaust manifolds for the 6's the same? Mine has some cracks and am considering replacing it.

As far as I know trey are all interchangable, but not the same exactly. There may have been some different bolt mount differences for choke heat shields, trhottle kickdown etc. I do have one or two extra manifolds aroiund here that could use a good home, and I even have access to a surfacing machine to make the mounting surface flat for you if that would help. Lemme know...

Do you know what engine size your extras came from?

I also had problems with my 292 and the exhaust. Just had the intake and exhaust manifold bolted together and then machined. got a new gasket and problem fixed. Don't forget to tap the bolt holes, shot them with air, then loc-tite.

I should have specified which gasket. I was talking about the gasket that is sandwiched between the intake and exhaust. I am wondering if the exhaust man. is warped and wont seal. I have some ideas. I have another 2 pc setup i think i will try to have surfaced. I am looking for which gasket material is best to use.

Try Remflex.com, I don't see the intake floor/exhaust-heat gasket BUT they have sheet pieces to cut your own custom shapes. Remflex are thick graphite impregnated gaskets.

I'm using one on the head to intake/exhaust.

When mine blew -used a flat file to dress the surfaces and make sure they were flat. I did chase all the threads - used loctite with a new gasket( stock type ) and coated both sides with ultra copper . I've used this stuff on headers before and had to beat them off with a hammer.
