so i had my head milled down because of warpage and I know about the infamous drivers corner bolt,so my question is i was gonna cut down drivers corner bolt 2 threads and the other corners 1 thread but should i cut down the middle bolts any because of them milling the head down?

NO need to cut the inner head bolts but all 4 corners need to be cut. They all need to be cut equal, the drivers bolt hole is the same depth as the other 3.
