What is the P/N for the tr6's? Is it 4177? I was running the AR3910's but they load up pretty easily and they're twice as expensive as the tr6's...and no one seems to have problems with the tr6's (I'm running stock heads) so I think I want to go that route.

ltl, the 3910 is a really really cold plug.. 3 heat ranges colder than the tr-6. but i agree that if you have stock cone seat heads that is the plug i would run.
tr-8 and 3911 are probably pretty darn close, exept the tr8 has a full tip and a cone seat.
anyways the new plugs work, but no better than the 3911's i was hoping were worn out. oh well trying something else now..
maybe get the valvesprings checked, maybe get someone else to try my injectors..maybe buy injectors.. maybe throw some money at a new cam/crank sensor

Bob didn't tell me about having to use gasket plugs. The heads are fine and I ordered the (7173) from summit last night along with a few other parts...

if the head has a tapered cone seat where the plug goes... it uses the tapered plugs like TR6s. the tapered cone is how it seals.. like an AN fitting.
if the head has a flat surface, perpendicular to the plug threads, then it uses a compression gasket spark plug... the gasket crushes to seal the plug...
