340 head torque requirements

340's changed head bolts. Same size, same length, better material. Went to 95 ftlb to seal 340 high compression engines. maybe across the board by date? 30 wt oil for lube. Beam torque wrenches stay in calibration. Rocker arm to 210 inch pounds. Using ft lb torque wrench at that low a setting is like using a sledge hammer to do trim finish nailing.

Between the change to composite head gaskets and better head bolt material will most certainly go with 95. Regarding rocker arm shaft hardware, have seen multiple but slight differences in recommended torques. My fasteners are not stock so the higher range will be used. Have a new 0-600 in.lbs. CDI torque wrench just for such an application.
