Customer: replied 7 years ago.
actually wasn't the crank sensor......apparently number two spark plug was broken during removal of the head......fixed that and it fired right up but was still overheating and pouring thick white smoke from the exhaust.....thinking a cracked head now.......so gonna replace that......what i do need to know is the proper torque setting for the valve rockers and head bolts......repair manual said rockers were 19.....and the head bolts were 43 for the short....46 for the long......all with an additional turn of 90 degrees........19 for the rockers turned out to be way too tight......wouldn't allow the motor to start.......as for the head bolts....43 and 46 worked just fine but the additional 90 degrees made it feel like the bolts wanted to snap at about 45 degrees of a turn so decided against following it past 46. rocker torque specs aren't too big of a deal for that i can adjust them manually with motor running.....though they would help.......but really do need the head bolt specs.....thank you for your time

the specs you have are correct and must be to this the rockers are not adjustable and the head bolts are not reusable if you reuse them and tourqe them they will break
