valves

[glenn in camino]

I just installed new valves in the engine I'm working on I set the clearances to .012 intake and .014 exhaust as best that I could. Some may be a touch loose. How critical are these settings?

Glenn:

Those are the settings you advised me to use years ago. All the engines in my Model A's have been set to those values and they have all run just fine. I don't think a thousandth either way would hurt anything.
