I'm not aware of a specification on that measurement either. I've always
used the rule of thumb that the ground flat surface must exceed 1/8" and
that it does not penetrate the edge of the outside dimension of the valve
diameter.

Dean and others,
I am looking for the thickness remaining from the top of the vavle
angle, to the top surface of the valve. All I can find in my books is that
you want a 'good margin' and that youdo not want to have a 'knife edge' on
the valve. The machine shop wanted a specific measurement, but I don't
think that one exists.

Howdy all,
I have my head for a 1948 A in the shop and I am
wondering the min. Valve heights for both the Exaust
and Intake.. For some reason I can't seem to find that
info in the books that I own.. I thought I had an I &
T manual around but it's well hidden if I have one.
Thanks!
Chris
