GN1 heads use tapered seat plugs. It appears some of you are using gasketed plugs on these heads? Gasketed plugs are designed for heads with a flat plug seating surface. There are not a lot of tapered seat long thread plug heat ranges available in a race plug, so if the gasketed plugs work on Champion GN1's it would make more choices available. Correct?
