got new exhaust manifold gaskets. one side is smooth metal and the otherside is perferated. which side goes against the head and which on the header. the ones i pulled off had perferation on both sides.

Shouldn't matter. Either side should be fine. It's all gonna get sandwiched in there regardless.

This...if it's stock to stock (manifold to head) it shouldn't matter. If you have an aftermarket exhaust manifold going on and the mating surface is a little rough compared to the head, I'd put the perforated side down then. But it all gets sandwiched together in the end...

Thanks, got it put on. I put the smooth side on the head. Seems to be working
