I sheared a bolt on my stock header flange so i figure as long as im taking that out to fix it i might as well install new headers.

I was reading some other posts on here and they were talking about the gaskets being a paper like gasket?

I'm just looking for somebody on here to tell me how the quality of the gaskets are with the kit. Otherwise I was going to get a set from FRPP.
