Re: Dished high head bolt
Domed or dished? I think I might have one or two high head type that are dished on top. Probable a supplier thing and was not tracked. If for the high head, sometime between introduction of that head and late 1925 or could be after market.
I know the voices aren't real but damn they have some good ideas!

Re: Dished high head bolt
1924 last use, have seem most of the pocket style high head bolts in 1922-24 cylinder heads. Some of the earlier flat head types can be found with Inspector marks on the head of the bolt.
From Bruce's C-D Encyl.
2-18-24 Redesigned, specifying threads to be rolled instead of cut. This changes the diameter of stock from .428 - .432 to .380-.384” and weight per 1000 pieces from 151.5# to 120#. (Rolled- thread bolts were used in all production after July 16, 1923 according to engine production records.)
6-25-24 Removed pocket from head.
