Do you mean run times? IE: Straight 1/4 track? Well my car ran its best 12.2 @ 110, bolt ons, stock suspension and when it was stalled automatic. Now it is set up do take the corners and more power from the heads and cam I just did recently. Just gotta get it tuned, found a tuner w/ a dyno at Bedford.

I wish i would have known this before I ordered mine. I ordered them and they emailed back and said Comp has them on back order for 2-3weeks. So I called every place looking for a kit in stock and finally found one. If I hadnt gone thru so much trouble to find a set I would have ordered from you haha

Roller tips will take the stress off the side load on the valve guides. This comes into play when you get well over .600 lift. If you look closely at the tip of where the rocker pushes on the valve stim, it starts on the inside and slides to the outside as it opens the valve.

yes, these rockers were updated after 2002 model year for ls1/6. they didnt get the tunnion bearings but they did get the larger needles like shown which are less prone to explode inside the valve covers. the larger needles can take more stress obviously. buuuutttt the trunnion upgrade is an excellent upgrade over anything. less friction=more hp and less weight=more hp. the stock rockers are lighter then just about any aftermarket rockers and alot more sturdier. they also produce the proper valvetrain alignment which=hp. without proper valvetrain alignment=failure. with adjustable rockers you literally have to adjust the rockers so that they work right. with stockers all you have to do is bolt and go. also with the trunnion upgarde, you can spin those things as high as you want them to go without any problems. im running .660" lift springs and .595" lift cam
