Fordson Series F Torque Specs.

"In replacing the cylinder head clean the surfaces on the cylinder head and turn the motor over so that No. 1 and No. 4 pistons are at top dead center; place the gasket in position over the pistons and then put the cylinder head in place. Be sure and draw the cylinder head cap screws down evenly (i.e., give each a few turns at a time)."

As you can see, very general. A local bolt/screw supplier can give you the recommended torque for the diameter and pitch of the bolt. I have a bolt torque chart here at work - but I have no idea of the nominal size of a Fordson head bolt. If you wish to email the size to me, I can look it up for you. I'm not sure whether they are made with fine or coarse thread since I've never removed the head from my '23 model F.

As to the sequence, start in the center of the head between the #2 and #3 spark plug holes and work out from there following a circular pattern. Set the torque wrench around 50% of the final torque and snug the head down - following the circular pattern. Repeat the sequence at around 90% and then again at 100%. Re-torque at 100% again after running the engine up to operating temperature. Do this final torque AFTER the engine returns to room temperature.

Something else on the market that Henry didn't have in the 1910's is a copper based gasket spray. I have used it on other engines with very satisfactory results and would certainly use it here.
