Plug to piston clearance?

I would think (depending on RPM, bearing clearance, etc.) .035 -.040 should be plenty. At .030 I have seen a bit of contact at higher RPM (7200-7400)

usaully if misses without gasket (.039) will be fine,I always make sure plug is'nt shrouded
by piston, probaly won't be on hemi style.
