Even tho this is not a Hudson but a diesel Cummins 5.9, I thought it might be of interest to some on this forum as it pertains to machine work.

    I have been aware of the use of plates when honeing but the demo showing how eaasily the bore is distorted by use of his hands!! good grief. Who woulda thunk?
    By the way. Years ago i had a 308 head converted to a boring plate by a machine shop. They used a fly cutter and cut six holes in a cast iron head. I loaned it to someone in South Florida about 40 years ago.

    I had a discussion with some one today about taking a cast iron head and making a deck plate out of it. I'll check with the machine shop and see if I can get one made up.

    Here is a note that Rudy B. sent to me concerning using a deck plate--
    But what we used is some very good head bolts with hard washers or spacers that you can find at local Hardware stores and use them. What you are after is to torque bolts to Distort the bore (so it will bore round) Use bolts washers or spacers just to load the Threads in the block. It works and in an old issue of the WTN there was a good write up on the simple torque without having to make a torque plate.
    And some machine shops use this same fix today.
    The only place that the bore is not round in next to the threads,the gasket does not distort the block.
    Does anyone know which issue of the WTN that article was in?

    Not the specific answer to your question ... but an index provided by Southern California Chapter that lists articles that appeared in the WTN 1960-2009
