ya super comps were hard to put in, i took the oil filter off, and had the motor out, so i put them in at the same time and were a b*tch especially since they are coated you wanna be careful. but ton of ground clearance, engine bay is tight. plugs are easy to get to, and just screwd my "race filter" back on lots of room.
just cuz headers are cheap doesnt mean you should get them. if you have any kind of engine they primaries are probably too small to handle the flow of the motor.
