Any valve lash advice from the gurus?

And if it continues to run too tight, say on a long trip, the valve will overheat and start to; lose it's shape, crack, or burn up. And then the pressure falls to near zero, and try to idle a slanty on 5 cylinders and you'll see what happens. With zero compression in one hole, it might idle a bit better than with one plugwire off.
But I gotta tell you, it's rare that just one valve burns up,lol.......
