Is overspray on cylinder head ok?

See your 1st pic with notch?? There should only be one on each shaft. As a preliminary "check" those go down and to the left when bent over dryhumping the fender.
Shafts look good. For a $4500 engine those should have been cleaned/polished already.
Polished up and smoothed out shafts they cleaned up nice and smoothed out the scores
