If you have too little preload, the valve train will be noisy and you risk exploding a lifter and having a very costly repair.Loading Radios, Transponders & Scanners. If you have too much preload and you have exhausted the adjustment of the lifter, the valves will stay open and the car will not start due to lack of compression. As you can see the stock rockers have a lot more room for error. Your goal is generally to have between 1/2 turn and 1.5 turns if you have stock lifters or 3/8 turn to 1/2 turn if you have Comp or LS7 lifters. Each 1/2 turn of the rocker bolt is ~.050 of lifter preload. Edit- Oh yeah, Yella Terra also makes a pedestal mount shaft rocker for the twisted wedge (but they dont specify if its for g1 or g2).

This is how much lifter preload you have. Standard rockers are advertised to fit, I dont know since I dropped full roller rockers on mine.
Continue to tighten the rocker bolt until the bolt hits its snug point. Everything past this point is lifter preload. At this point of first contact you are at zero lash. This way you can tell when everything first makes contact (the valve is touching the rocker tip, the pushrod is touching the rocker & and lifter and the lifter is touching the cam). With that lifter on the base circle loosen the rocker bolt and then re-tighten with one hand while spinning the pushrod with the other. Because one is open, you know the other is closed, meaning the lifter is sitting on the base circle. Turn the engine over so that one valve on a cylinder is open. To check for lifter preload or lifter squish you need to first get to zero lash. However we still recommend checking your lifter preload. The stock pushrods or whatever you were running will work fine with this rockers. However you should make sure that you have enough valve seal to retainer clearance to increase your lift.

They will work in all series II and III 3800 engines and do not require any supporting mods. These will work great in all applications: supercharged, turbo, or naturally aspirated 3800 cars. These have the upgraded trunion bearings compared to the stock rockers. By reducing the weight of the valvetrain, the valve spring doesn't have to work as hard and that will reduce the chance of valve float.
These are intended to raise the performance of an aftermarket camshaft by slightly increasing valve lift, reducing valvetrain weight (over 27% lighter than the OEM rocker arms, saving 2 pounds total!), reducing friction. The stock rockers are 1.6 ratio so these will increase your current cam's lift by 3%.
