What is the correct way to set the valve clearance?

Dang it somebody now.
The "book" says set them hot but I have found very little difference between cold and hot. I use various tools depending on what I can get my hands on at the time. 5/8" box-end wrench, set of thickness gauges and flat blade screwdriver to special valve adjusting tool with screwdriver/wrench in one tool. Always set them loose 0.006" (intake) and 0.008" (exhaust). Be sure to check the rocker arms to see if the ends are cupped or excessively worn. In that case using a feeler gauge will not give an accurate measurement. If I don't have "feeler" gauge handy just set them to a light click. Takes years to get a "feel" for the right gap.
Actually the best way to set valves is with a vacuum gauge. Though I don't often use it. Set each valve with hot engine running at slow idle to maximum vacuum. Works well even if rockers are a bit worn. It doesn't need a flat surface to get the gap right like the metal strip does.
How Sweet the roar of a Chevy four!

I always do my valves hot, but more importantly struggled for many years to get the feeler gauge, screw driver and the spanner to work as a team.
Came across a Snap On tool that's a combination of the screw driver and socket.
Man does that make it easier.
Cheers

Some say "Street is neat". I prefer "1928 is great" I have documented my 45 years with a 1928 Chev Tourer, from 1973 to 2018, and regulary add other items that I hope are of interest to others. Your comments are most welcome.The story of the Red Chev can be viewed at http://my28chev.blogspot.com/

check the lash with the feeler gauge. If it's too loose, then loosen the nut and screw together, turn the screw a tad clockwise relative to the nut, then tighten them all together (turn the nut and screw at the same time). Check lash again, if it's too tight, repeat but turn the screw a tad counterclockwise relative to the nut. usually only takes one or two tries when you get the hang of it. The feel gauge should have a slight drag when you put it between the rocker and valve stem.
