Here’s a chart that covers the bolt torque values. Your TN cylinder heads would be 5 to 7 ft-lbs. or 60 to 84 in-lbs. Use an in-lb torque wrench for the best result.
I use 2-stroke oil when honing cylinders and Lubriplate 105 assembly lube during assembly of the connecting rods. Cylinders should be well coated with 2-stroke oil when installing the pistons.
