alright well after the cam install (probably just a co-incidence) i developed an exhaust leak where the front header bolts to the crossover pipe. i tried just goop it up w/ some high temp rtv but it didnt work. so today i unbolted it and loosened the front header, and really caked the rtv on there, let it sit a few hours and put it back together, then let it sit about an hour and started it...still leaking. i didnt get a new donut gasket, but anyone else have any suggestion or the same problems before? thanks guys
