Have you reached the point of Long Branch is the only way to roll?

The manifolds tend to warp due to the lack of clamping pressure from the small number of mounting bolts. You have to get them machined flat or get another manifold.

Well I talked with the owner. I told him what I found he wants to have them fixed. So I'm going to try and find a machine shop to cut them down. He also said what option do we have to buy new? Any replacements out there? Steve you mentioned the ram air manifolds. I already have the exhaust bought and fit to these manifolds. Are the ram air manifolds a direct replacement to factory manifolds. I don't know the part numbers of the stock manifolds until I get them back out of car. I'm going to have both sides done.
