I could see how this would work if you were talking about a Hyd lifter engine. Im talking about a GTIR engine with solids, grinding down the higher one would result in the rocker being parallel to the cam, but leave the lash far off.
And before you say it again, no, non GTIR shims dont work on the GTIR head.
no it wouldn't. i'm done trying to explain this to you.
18 adjusts the clearance for 15 to the cam lobe.
the shim & guide combo serves as a purpose only to locate the rocker, and balance it perpendicular with the centerline of the base circle. set the balance by grinding down the higher one. then adjust the screw on the lash adjuster to get the clearance where you want.
and yes, they work.
