Yes, I should have said "warmed-up" settings. We used the +2 thousandths rule of thumb for valve lash on most of the race engines we ran on the dyno during the 20-minute camshaft break-in runs when it was not practical or prudent to stop the run for a more accurate hot valve adjustment. A slightly loose valve lash is much safer than one that lets the valves tighten up and stay open, even a little. All the loose lash does is make a little noise - - -a tight valve can overheat and burn during a camshaft run-in.
