Title: Need Exhaust gasket
If you're talking about the collector gasket, you're at the mercy of the header mfg.  There are no one-size-fits-all.  Drop one collector and trace the outline, bolt hole positions, and center hole diameter (probably 2.5" on a small block unless someone went nuts).  That'll give tech support something to go by.
 
If you're talking about header flange to head gasket, there shouldn't be that many for stock-type 350 heads.  They're probably either round port or square port.  You should be able to take one out WITHOUT dropping the headers.  Take out all bolts EXCEPT the end two (one on each end), just loosen those enough to let the header fall away from the head about 1/8" to 1/4".  All gaskets that I've seen have a slotted hole for the end two bolts.

Subject: [Chevelle-List] Need Exhaust gasket

Does anyone know what type of header gaskets would be used in a Chevrolet 350 sb?

I looked on summit web site and they had a bunch of different shapes and sizes.

How do I know which size to get without pulling the header off?
