1972 20hp Johnson Head torque sequence?

[dbiehl]

I was just wondering if somebody knows the torque sequence for this outboard and if there is a torque sequence/torque spec for the exhaust manifold and from what /i understand the torque value for the head is 96-120 in lbs. is this correct?

torque sequence is.....start in the center of the head, and in a "pinwheel fashion", move from the middle to the outside. ( if you search the forum, there are some diagrams) . torque to half value, then re-torque to final specs.
im not sure of the exact specs for your motor.
