Time to remove, skim and do the job properly I think

Time to remove, MEASURE and do the job properly. Heads don't just automatically need skimming!!!

Unless valve clearance is critical the head really should be skimmed unless it was done recently, particularly in this case where the bolts were swapped out on the car.

But what possible benefit is there if its a clean surface and you've measured the head and it checks out ok?
