My stock 292 in the shop has 2 studs, 2nd and 5th. the rest are bolts. They don't have washers they have little rocker arms for lack of a better word. I probably have a set off a 250, same head if they will work. I'll even blast them for you if you need them. I probably have some manifolds around, also 250 if you need them. No charge just let me know if you need them or anything else I might have laying around. I buy 250's and just keep the heads. I have a few laying around. Hope this helps.
