I have a Protec rec head with half girdle on my 701. I recently removed it and can't find my torque specs for re-install anywhere. Anyone know what they might be?
What torque to use with protec rec head+girdle on 701?

Absolutely not! The head bolts are 8mm, and Yam recommends first step = 11 ft/lbs, 2nd step = 22 ft/lbs. At that torque
they are just about ready to strip the threads in the cylinder, so if using a o ring head, 18 is quite sufficient.
I think the girdle retaining screws - the long ones which screw into the cylinder retaining nuts- are 10 mm dia.,
they would be torqued to first 17 then 29 ft/lbs.
I think post #2 spec refers to Nm- no one uses that. M-kg would be 1.5 and final 3.0
