The YT instructions aren't very good, set the wipe first then measure for pushrod length. The instructions cover several of their rockers and give the false indication that pushrod length determines the wipe pattern, which it doesn't for these rockers.

Does this kit come with shims?

I plan to:
-Mark the tip of the valve tip w/marker.
-Set the valve to zero lash and tighten, making sure I get the preload I want using adj pushrod.
-If preload is good, roll the engine over. RR should start on the top side of the valve tip and by mid lift be centered.
