What's the procedure, for adjusting valve lash, and what is the spec for the '59 223?

 

Valve lash for a '60 is 0.019, hot or cold for both intake and exhaust, kind of straight forward.(Which I am sure it is the same for a '59). Take the valve cover off and then start it up and adjust while running with go-no-go feelers guages, at least that is how I've done it. Just don't wear a hooded sweatshirt with the strings hanging down or you may get caught. Kind of hard on the back too.
