I've had Harland Sharp rollers on my ls7 heads for over 2 years and no problems. Cam lift is almost .650

I think they were around $500

Man ive had the trunion upgrade in the trunk of my car for months now. Been lazy. Lol. My stockers have been holding up tho for a while with a .641 lift cam.

lol I guess you dont need the upgrade then, you passed the test..

I went ahead and got the set of CHE ls rockers since I got a good deal on them, expensive but oh well...

Yeah theyve been on there since July of last year. I have PRC .675 springs too which are rated at 490lbs @ .675 so the rockers see plenty of pressure and lift. I check them every few weeks but I've had no issues yet even after a few hpde and plenty of top end runs. Guess thats why ive taken my sweet time to do the trunions. Its all about having the right valvetrain geometry.
