[Tigers] large cheddy valves

[Clyde McLaughlin]

years ago I repaired two sets of heads that had the longer valves and screw in
studs installed,  when the engine got past 4 grand the rockers arms broke due
to insorrect geometry...the bosses in the heads need to be milled down for the
screw in studs a the valve stems need tobe shorted,  this done on a valve
refacing machine,  it was to long ago to give measurements,  but Ford hot
rodder macine shop should be able todo this their sleep,  Clyde 382001173
