Dont the LS7 lifters have a higher cup than the stock ones? Might want to measure the preload just to be on the safe side.

I thought the same thing but GM now lists them as a stock replacement for all Gen 3 motors as far as I could find.....

You should ALWAYS measure the length. The easiest way to do this is to turn the bolt down on the rocker until there is zero lash (rocker tip is just touching the valve tip). Count the turns until you have reached your 22 FT LBS of torque. Most people shoot for about 1 1/2 turns. You don't need a pushrod length checker, but they are a nice tool to have. This method is for non adjustable rockers.
