>>>*I confess to being easily confused, and I have one here that has got me baffled. I have heard this same complaint before.

*Customer states that our exhaust manifold gasket has rivets that won't let it seal....? I get the same report, maybe one out of 400-500 or so?

I grabbed a head and checked, the rivets clear. I went and bought a competitor's gasket, made exactly the same way.

Can someone tell me what the combination is that causes this, or what the gentleman is doing? I said "wrong head", he insists it is correct and the one he took off did the same thing.....*EB
