LS Rockers Upgrade I have a mildly built LS1 in my 99 formy...i want to upgrade the valvetrain so i can spiin her to about 7500 RPMs...what kind of valvetrain is available for this build?
the car will be h/c car with forged bottom end..and maby some spray as well..i have seen the scorpion rockers/ fuel rails etc..and they look nice..but are there any particular gains? hp/tq? reliability issues? warranty? i am curious as to who has what on their cars and or any problems that they have encountered with aftermarket parts.. thanks in advance

Are you gonna run a solid roller cam? If you are thinking of going that high of an RPM you are in that arena. I would consider it because the 98% majority (That I know of) hydraulic roller cams fall off at 7200 for the latest. Either that or stick with 7200ish.
Maybe the stock upgrade from Nasty Performance would be the way to roll. It is cheap and is a strong/reliable rebuild.

crane quick lift rockers is what i would put on it, lifters wouldn't hurt either. 7000k+ capable, but motor will fall off on power way before then. dual springs will be a must, along with lightweight valvetrain components to help reduce harmonics or float issues.
