I have clips that I bought to hot adjust SBC valves. The clips slip over the end of the rocker arm and block the oil hole in the rocker from the supply oil up the push rod. I got these after making a real mess a few times. The hot oil wasn't fun either!
I ended up measuring the hot to cold clearances and adjust them cold now. The difference is .001" greater for the intake and .0015 for the exhaust on my cam.
Not applicable for the Flathead of course but I thought it might be interesting to some of you guys.
