No worries and thanks for checking in. I wasn’t super concerned, but you could stuff some paper in the holes or carefully tape them off. I did have rags in the intake ports and covered any areas that I thought might get paint into oil passages. Personal preference really, can’t hurt to be overly cautious. I like to run a tap into all of the holes I’m using, too, especially with an *ahem* gently used engine.

Valve cover adapters I simply sanded and used a self etching primer to help the paint stick to the aluminum.
