Who can tell me how much i need to have milled off the bottom of my stock 760 head to get around 180psi compression?

Just swap to a 61x head. Shaving a 760 head will still net you uneven numbers because the rear dome is larger.

Will that punch my compression up a bit?

.040 thousandths will get you 185psi. with a cometic head gasket.

Silly question.
64x - 760 piston is 84mm and a 61x - 701 is 81mm
Wouldn't the squish area be all messed up because of the 3mm smaller head dome diameter of a 61x - 701 head and a 64x -760 piston?

It would be fine. I have ran a 61x cylinders bored to 84mm. With a 701 Ada head. Would it be better...yes but I don't think it matters that much in a budget application.

I was just wondering if the outer edge of a 84mm piston would come into contact with the narrower 81mm dome of a 61x head.
On that note, does anyone reshape standard head domes or is that only done with removable domes like ADA?

I have looked in to recuting the domes. But there's not a ton of material there. I may try and look in to it again since I have a larger lathe. I just need to see if I can swing it in the chuck. I think I could re cut the squish but not sure about the dome.
Some one with a head on hand measure from the center of one plug to the the furthest edge of the head.

7 1/2". You'd need a 15" swing. Some have reshaped domes with a mill using a homemade cutting tool.

Hah. Crap I have a 14 " swing. Any way I just bought a rotary table and could do it in the mill but the lathe would be cheap and easy. If it would work.
