If by chance there is some type of debris under the valve and you are able to knock it loose, where does it go?
Hopefully not between the piston and the cylinder wall but hope should not be a plan.
I don't understand the apprehension in pulling the head?

Yep… My thinking as well…

Reading about sealing the intake manifold it probably takes one day to just clean the sealant off.. Still wouldn’t stop me pulling the head..

And lapping compound is like fine sand in a paste.. and absorbs the metal ground off…. Rotating will sling the paste… and it will dry and fall in…
