Yes I have arp head studs:

the head should have the surface u descibed after its been skimmed. if i was u and it was a customer job id be inclined to do the deck aswell, but then again its not my time or money and if it doesnt seal u wont have an angry person in ur face

Measure the block and see if it has any warp in it. I had a copper gasket made up for me, skimed the head, no pitting on the block used the VHT copper stuff and put it together. Had no compression in two cylinders.

What is the advantage of flat unbeaded copper or metal gaskets? are you trying to increase quench efficiency or compression ratios or what?. Are they superior to standard gaskets in what way???

Ive never used them before? only on some diesels but they were shimmed type gaskets to get the correct compression ratio back after milling.

Another reason is that you can re-use them again. Well the copper ones anyway. I thought i could save money if i needed to take the head off again.
