My daughter is an auto machinists, mainly diesel...but isn't versed in part quality yet. Neither am I
I'm in Industrial Heat Transfer..
the heads are decked to meet new flattops and she has guides waiting on her. Just wondered if the quality of SS or production is better at a specific Factory.
thanks for your help man

The stock 400 valves had a multi grove retainer. It’s recommended to change to a standard single groove type valve and retainers. Stock material valves should work just fine for your build but performance valves can’t hurt.

Manley has always been the gold standard. I just never cared that much to be honest any good brand works fine.
If you're doing much surface machining be sure to check your lifter preload and geometry good. and I hope if you have a flat tappet cam you bought your lifters a while back. there seems to be a lot of break in failures lately I think since Johnson went out of business it's a crap show. some engine shops are refusing to warranty flat tappet failures now.
