    hi I just bought a complete exhaust system to bolt up to my stock 69'gs 400 stage 1 exhaust manifolds,
    Is there a flange gasket or donut that goes between the manifold and down pipe?
    Also the heat risers still there and I was going to remove and weld up the shaft hole.
    The manifolds are in pristine condition and definitely useable.

    There is a gasket between the heat riser and manifold on driver's side -- no others -- to my knowledge. I left my heat riser in-place and just wired it open (it was broken beyond repair anyway) -- but i could see why you might want to be rid of it...

    The reason I asked about the flange donut is the mating surfaces have about 1/4" play in them?
    im not sure what the fix is here or why the figment is so bad?
