Hmmm, got me thinkin' as I run a couple of Dorman studs on my Victor/Sharp setup. I don't remember why but, like you, I'm sure it was because I couldn't find the right length ARP at the time. Dorman did list as grade 8. Are those stands positively located or just located by the studs? I remember your center rocker stand issues from a few years ago which prompted me to install inserts deeper in head before bolting them on. Thanks for posting back then. I hope your valve train issues go away soon...
