Motorcycle Repair: 1970s Honda ct 90 trail bike, copper head gasket, torque chart

Question
I was just wondering if you knew the torque specs. on the head bolts for the 1970's Honda ct 90 trail bike? It's a CT90E if that helps at all.

I don't recall if they have 6mm or 8mm studs. Use around 5-6 ft lbs for 6mm and 12 ft lbs for 8mm studs/nuts.

I can do them by feel, but if you don't have the "feeling" of tight bolts then use a torque wrench. Use a cross pattern, starting at about half the specified torque and increase a little at a time. It isn't all that critical on the 90s due to the copper head gasket ring. Just needs to be equal on all 4 corners.
