    my 430 shop manual says "being prepared" for your specific chapter

    but on the 360 manual it reads:

    tightening of cylinder head(pre-tightening to 60nm)
    thread: m11 x1

    min torque + min angle 60+24 degree (A)
    max torque + max angle 90 +76 degree (A)

    replace "degree" with a Celsius sign.


    I am not sure what degree it is talking about.

    On my F355. Head/Block Studs are torque to stretch under load.
    Pre-tighten to 60 nm.
    Then tighten to a specific angle. 90 degrees if I recall correctly.
    No specific torque value as used on earlier heads.

    Giving this guy specs for a 360 and a 355 is nice and all but 430 is a completely different engine.

    I would surely like to know what Celsius has to do with a torque spec.

    It's call torque + Angle. The degree, is not temperature, it's angular degrees.

    It's the amount of rotation beyond once the torque is met. It's a common fastener tightening strategy.

    Also, need to check to see what, if any, lubricant is to be used on the threads. Improper lub yields improper torque.

    Correct. Molykote is used on the 355 but I'm not helping the OP with this post as he has a 430 :)

    I scanned the 430 WSM I have and could not locate the info...

    WSM has this:

    Molykote 1000
    60 Nm + 90 degrees to 80 =/- 10Nm
