Head returned with concerns

[Falcon62]

I didn't get the head decked, but the machinest did say that he resurfaced the head incase of imperfections from the past (guessing that was milling the head?).

Yep, that's what it's called. You 'mill' a head and 'deck' a block, but in reality, it's the same thing either way, removing surface material to ensure a truly flat gasket mating surface.

Generally speaking, resurfacing either a head or block is taken to mean a light, cleaning cut. While milling or decking is generally taken to mean a more aggressive cut intended to remove larger amounts of material either to reduce deck height on a block (hence decking), or reduce combustion chamber volume on a head. 8)

Sometimes, resurfacing may turn into milling or decking due to the amount of material necessary to be removed to 'clean up' the surface, or as a result of mutliple visits to the machine shop over the years.

New lifters on old cam - no problem! Just break in like a new cam, with cam lube. Other way round is not so clever or predictable.

And most likely guaranteed to fail.
