Default Re: Why did they use metal valve stems?

From a reply to the valve-stem question on the AACA Forum:

"Per the judging guidelines [ AACA ]... Valve stems must be metal prior to 1930 and must be the same as originally supplied on the vehicle. Documentation may be required. Fords will have metal valve stems through 1934."

Incidentally, this reply was from a Model A guy who hangs-out on the AACA forum...
