Cool

Do you guys cut and trim these gaskets to look like the ones in header install kits or just lay em across and bolt on headers?

I installed SLP headers using Mr. Gasket Copperseal gaskets. I placed them with the mr. gasket logo facing out which put the raised part of the crush area facing the headers. You need to put the raised part facing the block. The ports on the headers where large enough that they didn't overlap with the crush area on the bottom of the port and the resulting crease caused a small exhaust leak. There wasn't really bad audible ticking and only the tiniest amount of soot visible from the outside. At first i thought it was just the extra noise of the headers.

just a heads up.

Thanks, that is good to know. This is one area on our cars you don't want to address on a frequent basis!
