      I am looking for a torque sequence diagram for the 10 bolt OMC cylinder heads from the 1940’s and 1950’s. Much appreciated if someone can post one here. Thanks.

        You always start in the center, and spiral outwards. Start with 1/2 torque for a round, then 3/4 torque, then the final torque. Every time, starting on a center bolt, and spiralling outwards.

        9……..10
        5……..6
        1……..2
        4……..3
        8……..7

        Imagine each number here is a head bolt. Rough draft, but you get the idea.
