But you can safely go to 44 ft lbf. Then - reset the valve gaps..... 12 thou on inlets and 15 thou on exhausts.

You did set the smaller rocker shaft nuts to 25lbs/ft?

Must have - cos they would strip/snap at 40.............. :o
But they should of course be finally tightened down AFTER the head nuts have been torqued down. Before that they should just be nipped up lightly - and NOT used to pull down the rocker shaft pedestals.......
