Rollor rocker valve adj

I just had a rollor rocker setup (uses stock pedistals) put in my pull truck (12v cummins) stock ratio.. my question is how do you go about checking valve lash (where to check with feeler gauges) and at what specs are they supposed to be with this setup? Thank you ahead of time for any help.

This might help: the feeler gauge goes between the valve stem and the rocker tip.....and if you have to ask that particular part of the question...I would suggest you get some help your 1st time doing this.

with #1 piston TDC on compression stroke (#6 rocking) you can set:

Intakes 1-2-4
exhaust 1-3-5
set intakes to .010" (or the cam's recommended lash)
set exhaust to .020" (or the cam's recommended lash)

find #6 TDC compression. mark crank damper and gear cover turn engine over 1 rev. you verify this when you see #1 valves go into overlap (rocking).

now you can set rest....

intake 3-5-6
exhaust 2-4-6

I've done them on a stock setup. But wasent sure where the feeler gauge goes on a rollor setup. So the feeler gauge goes between the bottom of rollor and the valve stem ? Do you still use the .10 and .20?

yes....if cam is stock...
