RHS head valve train geometry issue

yeah. not really gonna hurt anything like that.

maybe lose a lil lift, but nothing harmful

good to know .... my LA X had the wipe pattern just to the exhaust side of the valve stem .... I have 1.6 PRW stainless

this may sound stupid.... but could I mill the shaft groove deeper to improve this? or would that do nothing.
