Long valves on W2's with .600 lift?

Krooser said
I'm using T&D rockers and they specify the 5.140 valves. They sell rocker stand spacers that allow fine tuning the rocker stands to get the rocker tip sweep correct.

I've talked to them a couple times and they have been very helpful even to a schmoe like me.

Do those rockers come with their own shafts and stands, or are these econo heads?? I forget easily.

EDIT. NEVER MIND!! I went and read the first post. What do the shims look like that T&D sends out??
