Never done intake/exhaust manifold work. I just order a new exhaust manifold for my heep because the old one was cracked bad and was loud. I got the new one in the mail today and opened the box up and inspected the gasket right away. It was left sitting upright against the door and the manifold was on the gasket in the box this way. There are some minor creases in the gasket. This won't affect anything later on will it?

Myself, I'd buy a new gasket. That one may work ok, but I wouldn't trust it not to leak.

A dab of black rtv silicone and it's good to go. I generally put a very thin coat of rtv around both sides of the intake gasket (the intake portion in this case) just to make sure nothing leaks. It's probably overkill, but that's how I am.

The gaskets are cheap. Nuff said.

Well i wouldn't go buy a new one because they packed their products crappy. I think it should be alright was just wondering if this wouldn't crack more over time because of the heating and cooling?

Very good possibility it will fail. That's why I suggested getting a new one. Or, go ahead and run that one and when/if it fails take the intake and exhaust off again and replace it then.
