well its now a week later and i have the cams in and the motor running. I dont think you guys understood me but i'll refreshen. Ok my rockers fell off and damaged the lobes on my stock TT intake cams (both arent i so lucky). the dealership stealth manual says that the intake cams are the exact same for n/a and TT. they are stamped with a J. The exhaust are the different ones. N/A should be a k and the TT should be an N. so since the manual said the intakes were the same i stole the cams out of my buddys na motor. a month later when i put the heads back on, i grabbed the cams to check which were which I noticed the N/A cams were B on intake and F on exhaust. found out later that there was two different models of n/a cams. so it turns out i got that model and the only difference i see is that it has .0235 more lift and not any more duration. in theory this should give me more low torque off the line, and raise top end because more power is made due to more lift cuz more air is going in the motor. Oh and yes the DOHC N/A has more compression but its not cuz the piston comes up higher, it's just that it's domed and the TT is a dish. The intake cams are supposed to be exactly the same unless you get the other model like i did, and yes the heads are exactly the same, which by the way flow very poorly, i suggest ripping them off and porting the hell out of them but keep in mind that bigger is better does not apply, just try to make smoother flow. if i can figure out how i can send pics of what i did to any who would like them. thanks for the replies
