Take the heads to a shop and have them redone correctly. Mopars have rocker shafts and all the stem heights should be the same. Sure you could use adjustable rockers but that would be just a bandaid . Cutting the valve stems could result int the rocker arm hitting some of the valve spring retainers. Sorry for the bad news but the shop you used Fudged your heads up. Go have seats installed and buy new valves. Don't use that machine shop to do it.
Aske to see their head machine. They don't have one . If they did all your valve stem heights would be the same . They did them with a manual cutter
Could you imagine that shop doing 4 0r 5 valve heads with fixed rockers
3rd pic is our head shop manual machine, 4 and 5 is our digital machine. 5 valve heads need a special fixture 6and 7. Shop puts out at times 20 -30 heads a week. we do all the new 2022 and 2023 Ram heads for dodge dealers. The seats are falling out of the 4500 and 5500 comercial diesels.
