Yanmar torque specs

Doing some work to a friends Yanmar 1100D, I need to know what the head bolt/nut torque is. Also if there is a specific sequence that will be helpful as well.

Thamk you

Found a tag on the block with 2T73 is that the model number you need? There were some nubers but they were rpm and liters.

Thank you

Sorry my list of head bolt torques doesn't show that model. You might try asking over on the Yanmar forum Yanmar - TractorByNet.com

The book I normally use doesn't list the model you need but here's the link to it.

I do have the service manuals for the Cub Yanmar tractors but they use a different engine.
What are the diameters of the head bolts?
Here's the chart for the Cub Yanmar heads.

I finally found some service info on the 2 cylinder Yanmar.
