I have the manual on that engine but before I post I need the model number off the rocker cover to give accurate information, should be like a 6067gk or wk.
The 60 ser manual listed torque for nuts and bolts that are an exception to standard torque, meaning iuf not listed then use standard torque, I'll list a link at the end.
All in ft lbs. unless noted.

The rest are standard on the chart from this link, be sure to coat all threads and head with oil except the head bolts as stated above.
