Neck marks look like excessive ejector pressure and a barrel extension which needs "melted". An AGB might only slightly help that issue, but the solution is really to balance your ejector and dehorn the lugs on the port side of the extension. Less gas will help with your CHS, adding some carrier or buffer weight may help too - but the AGB is the best path.
I'd never drill a hole in the side of any of my bolt gun barrels (which didn't yield compensating benefits), so I'm not a fan of off-bleed gas blocks either.
When you say to deform the port lugs, do you mean to round them over or what?
