Comp Cam 1.5 roller rocker arms?
I was given a set of 1.5 RR. They have 10k miles on them and look in great shape. Would I gain any power by replace the factory arms with the RR? Any help it great

Less friction...dunno of anything else. It can't hurt anything, and they ARE free !
1.6's would show an improvement (from what I've read, no personal experience here) if you dont mind throwin some cash down. IMO free is better!

someone dynoed a 25hp gain with 1.6 rr and an lt4km...so you may see about half that since you won't be gianing any lift. but for free...who cares.
just make sure you get an lt4 km to compensate for the added valvetrain noise. also you may want to figure out if they are self aligning or not. that is very important.
some guys are running a mix of 1.6/1.5 on their intake/exhaust valves...not sure of the advantage. but maybe you could pick up a half set of 1.6's to see what happens. would be an interesting experiment.
