Head Torque sequence

[suri1993]

I am helping my neighbor replace a head gasket on a 1970 70 H.P
Chrysler outboard. Can anyone tell me the Torque #'s and Sequence.
Thank you

Re: Head Torque sequence

225 INCH pounds in two or three steps, start at around 150. Start in the center with the two widest spaced bolts and work out in a spiral pattern. This keeps the head from warping. If it is a new head gasket, after running for a while, retorque the bolts.
