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

Under the roller and top of the valve like a stock valve adjustment. I bet 20/10 would work just fine.

I suggest “side to side” and not “with” the roller. Going “with” the roller may give you a feel that it is looser than it feels.

I slide the feelers gauge in from the side of the roller.

Okay, thanks guys. Should I stick with the .10 and. 20? It's a big billet cam. Or a lil looser say .12 and .22?

Defiantly not looser. Sounds like you should talk to your cam manufacturer or whoever did your cylinder head.

I ran mine a little tighter, as I knew I had plenty of piston to valve clearance. I was looking for a little more cam.
