yes, I broke it in with that plug (c6tgc). I also have a c7tgc plug, i suppose that's what I'll have to use once the weather starts living in the 90's and above right? also I noticed that with the plug out i can turn the flywheel all the way around. it gets a little snug at TDC, but i can roll it with my thumb. normal? can you explain what "drops its nuts" means exactly. does it mean that there's no pinch at TDC?

side note-it's mounted on an 8ight t 2.0 with stock exhaust. I'm thinking it needs an 086 pipe? I'm also not sure on the manifold. novarossi recommends nvr41019(short offroad) 41020(long smooth flow offroad) and 41021(short smooth flow offroad). I think my stock one is like the 41020. any suggestions?(other exhaust combo's?) probably a track specific thing but fastlane isn't done building the new track yet, so i don't know what it's going to look like.This will be my first attempt at racing, but i don't want to be slow. thanks
