Replacing the gaskets for the intake and exhaust on my 228 and the kit came with both the metallic ones and these paperboard type gaskets. Anyone know if I'm supposed to use both, or just one or the other?
Turns out it's the paper one! The kit from Classic parts has an oversized metal face gasket, and a proper sized paperboard one. Must be to make sure it covers both large port and small port intakes for 270s and such.
