this is the Fel Pro 60538.  all metal.  worked great on my passage side.  didn't work well on my drivers side.  I guess its all in how the flare on the exhaust pipe is formed.

Try looking through the Rem Flex catalog.  They make excellent gaskets.  I use the exhaust manifold to head gaskets all the time and they never leak.

I've blown out probably a dozen of them on various engines, yet not one of the sintered graphite type ones has blown out. It's enough to convince me. 

Hi everyone... I ordered the NAPA/WALKER version that was suggested. I'll find out if they work on Monday!

The Fel Pro's I mentioned above are not blue whatever. They are 100% metallic and if I didn't know better would say they are a lead alloy with asbestos in them of some type.  Of course with todays regulations they aren't but they are definitely solid....

Don't get the Fel-Pro ones. They are made of a blue paper-like material that turns into powdery ash once it gets hot. Then it blows out and leaks. I've driven myself to the edge of insanity trying to keep them sealed. 

Get sintered graphite ones made by Walker. You can order them from any NAPA. Walker's part numbers are also NAPA's part numbers.

Walker/NAPA part number 31507. 

Exhaust gaskets went to crap when they stopped putting Asbestos in them.

Fel pro says use the 2-1/8" which is what I have on my 72 manifolds.  However, like I mentioned they don't fit tightly and don't "snap" into the manifold like the old ones did and one side leaks ever so slightly at the manifold/donut interface I believe.  It appears the 2-1/8" donuts seal fine on the exhaust pipe side.  So I just ordered the 2-1/4" to see if they fit tighter into the manifold and help with that leak.  If the 2-1/4" don't fit the manifold then my plan is to go back to the 2-1/8" and use high temp copper RTV stuff between the manifold and the donut.  Honestly, I never had so much trouble with this sealing over the 30+ years I've had the car....
