When I bought the car it came with a fully rebuilt motor and worked p90a head. I did not know enough about Zs to ask what type of head gasket was used. This coming from a guy who spent a week researching pointless distributors just to find out I already had one in the car, doh.
Anyways, I was wondering if I already have a metal head gasket since I ran a conductivity test with my multimeter (placing probes on the gasket) and it shows it conducts electricity. OR do all head gaskets come with a metallic conductive outer edge?
