Smallish point...bearing area on the valve stem as drawn is pretty small...more bearing area (length) will reduce the requirement for precision fitted pieces, and help with controlling leakage during the firing cycle. Also aids valve stem alignment when the stem is re-seating.
Transfer porting as drawn will detract from performance...it's not just a "flow area"...it's dead space.
Edit: Ah hell...this always happens to me.
