Heat riser gaskets
I'm swapping out the unknown exhaust manifolds that Bubba put on my car next weekend so I'm ordering all the gaskets and hardware now...
There's no riser nor riser eliminator on it now but, I'm adding a spacer. Aside from the triangle gasket on the one side of the riser, does it also get the doughnut type gasket on the other end like on the driver side?
Mid America has a sleeve type gasket for this instead of a doughnut- does this work?
If it matters, it's an 80, with a/c and no emissions stuff.

There is a donut on the right side. On my Corvette Central exhaust the donut goes around the sleeve in your pic........

Interesting... so, I need that sleeve AND a doughnut on each side? Any chance someone has a diagram or explanation of how each side goes together from the output of the manifold and the pipe that bolts on to it? Because Bubba has something completely wrong on mine, I can't tell by taking mine apart.
