Gland rings counter bore
Does the block have a counter bore for the gland rings like the exhaust manifold do? My block doesn’t show any sign of any counter bore.

See page 312 of the Service Bulletins. Looks like the counter bore ended in January 1929.

From Bratton's catalog. The 4 rings that seat into the manifold and block to prevent leaks. Ford discontinued using these for a brief time in early 1929. If the manifold or block has been resurfaced, the width of the gland rings will need to be reduced by the same amount. __________________ |

Thanks. I think my block was made mid year in 29.

Re: Gland rings counter bore
Steve, Thanks for posting that info... well done and very informative. From one that had a background in automotive engine manufacturing, each one of those seemingly small changes brought back (bad) memories, of piles of paper work "change orders", foundry pattern changes (many - many patterns) and hard tool and fixture changes on the machining line.
