Need to replace the exhaust gasket
I understand we have a heat riser on passenger's side, will replace it with a 1967-1981 Camaro 2" Exhaust Manifold Heat Riser Eliminator, Small Block as nothing was on the line up to know (and exhaust was "leaking")
So I have to use 2 gaskets on each side of this "heat riser"
Then on driver's side, I have a "donut" which I found with vendors, however is this shorts stepped sleeve a normal set-up and then do I have to use a 3rd flange gasket on this side?
I also see several different gaskets at RockAuto with subtle differences. Anyone could point out the ones I need.
Current donut is about 2.03", stepped sleeve is 1.76" on small part, Manifold studs are 2.73" center to center (I assume 2 3/4")
