Leslie, I had a similar problem on my 81. After talking to a few z people I was told it is common for the exhaust manifold to warp on z's. They said it was no problem to take it off and shave it down. My local dealer said they've done several over the years and would run about $150, unless a stud was broken. Well, getting in there a stud was broken and it cost more.

Anyway, point is don't just change the gasket, check to see it is not warped. I'm not sure if that was a problem on the '83's but my guess is they're all prety similar. I would not wait until a stud breaks off in there. It did fix my problem.

Good Luck,
