On the left, you can see the almost brand new " LS1 " rocker arm. On the right, this is a factory 03 LQ4 rocker arm. You can see there's a difference in en angle of the "tip" and the bearing is not the same.

This rocker looks aftermarket. Whose? Good question! The bearing is a different type than the factory type.

That explains why he was given 12 of them; a complete set for a V6.....

Correct me if I'm wrong, but I believe the 4.3 rockers are 1.6 ratio and the LS rockers are 1.7. From the first shot it looks like the push rod socket is a little further from the rocker fulcrum than the LS.
