It really depends on the cam and the cam grinders specifications. If it is stock, then it is Fords specifications.

In .012 Ex .014 too tight just take time grinding the stem. I made a fixture just a piece
of pipe that fits the valve stem and clamped that to the side fine grinder wheel. As I grind and rotate the valve to the wheel just nipping it check & repeat. Lash too loose, then you
have to reface the valve and or the seat, to set it deeper.
