There have been a lot of posts regarding the GMPP Guideplates wearing out real fast due to not being hardened.
I myself experienced some wear in a set after about 4000 mile use.
I found that the trickflow guideplates for the LT1 heads have the same spacing and are hardened.

Feedback: The above trickflows I referenced fit great on my stock casting LE2 heads. Rockers are centered on valve tips. About .014 pushrod-to-guideplate clearance with Comp Hi-Techs. That's enough to let the rocker pivot so either edge of the roller can slide over to barely hang off the edge of the valve tip when the rocker is twisted on the stud. But .010 is a lot less than the .025 acceptable clearance I have seen referenced here.
