0n my 2002 2500Hd Vortec 8.1. What are the valve lash settings?

Hello, That machine shop would be buying me a new head. Sure, you can use sealant, but considering that stud is going to get hotter than anything else on that engine, you will likely have problems with it. Watch for a stream of white smoke if you run it. No need to set the lash, just torque them to spec. My guide shows the studs are 37lb.ft and the rocker arm retaining nuts are 19lb.ft. Check your guide for the torque specs as well, however. The net resulting lash is correct if all components are serviceable.
