Part # for efe valve gasket(s) 83 olds 307 y code ???

[jim83]

I managed to get an in box nos efe valve - but no gaskets. Please if you know the part # s for the flat 2 hole side & does the "cone" side use a gasket, if so the p/n for that also. Azone, orielly , napa etc dont stock them so can't do an eye match.


Trying to get everything possible before starting the job. Thank You!!!

My original exhaust had no gasket between the EFE and the exhaust manifold. If I recall correctly, the EFE has a raised 'cone' in the casting where the flared end of the Y-pipe tube mates.

Looks something like this below. Goes between valve and exhaust manifold (flat side of EFE valve). As previously stated, the lower pipe uses the conical side to seal. Sometimes if the cone seal area is a bit pitted, you can always smear some exhaust sealer paste on it before bolting up the exhaust.
