Alex pegged it re: drooping manifolds. Easiest way to check would be to trial fit the exhaust manifold with gland rings but without the gasket. It will either go or it won't go. Depending upon the amount of droop sometimes you can get #1, #2 and #3 to fit in but #4 won't. At least that way you know the front gasket is liked up properly.


Of course, the ultimate solution is a new exhaust manifold. You get the benefit of a well machined surface to mate the exhaust pipe to. I've had to replace exhaust manifolds in both of my Town Sedans.
