Beater,
I am using BB chevy rocker studs on all the inline heads. Have been using just about any brand and been just fine. the problem we ran into is these particular castings are somewhat different, cast in the 90's. The rocker stands must be taller and thru us off with the normal amount to be taken off. We ended up using ARP brand rocker studs. The portion where the bolt head is has less thickness for the head(top to bottom). Gave us the room needed this time to clear the bottom of the rockers. This head will still get remachined after all the running. It will probably see another 25 or so runs. Tom
