Done some searching and haven't found a thread of this nature yet (unless I missed it)

I've heard alot of pros in swapping to Roller Rockers. One or two people out of a hundred say they're a very bad thing to do, but that's all I hear. Alot of people agree they're a great change, if only for the fact you're lowering the inertia force on the rocker. I think I said that correctly..

It just seems like common-sense to me that lessening friction is a good thing. I'm not going at it for a power-gain sort of thing. I just put a new cam in, .612 lift. 1.7 rocker ratio, Comp chromolly pushrods, new Comp lifters, new valves--basically new valvetrain all the way. I've got some Harland Sharp 1.7 Roller Rockers sitting on my desk.

What are the opinions & pros/cons of changing the stockers out for the HS rockers? Out of several forums, a few weeks of searching, and close to 100 opinions, 2 people said they'd suck power from my motor and could cause excessive wear. The rest say it's a positive upgrade, and vary with opinions as to why. Usually a slight power increase but most report easier on the valvetrain to move the valve.

There will be times I sit in the high-rpms, just to answer that question up front. Just looking to get all sorts of opinions.

Well I went 10.17@132 with stock rockers spinning it to 7200rpm. I switched to Comp Roller rockers just for a piece of mind and for valvetrain stability. I now spin the motor to 7500rpm with no issues.

I am using the HS on my 408 ls2 stroker motor no poblems. I used them on my ls6 motor running them up to 7200 no problems there. I guess that i have not seen the problems some must be havinig with these rocker.

There is little if nothing to be gained by replacing stock rockers, in fact there have been more problems with aftermarket.
