somebody want to give me torque values for head?

my research has led me to believe that they designed the motor to work with an asbestos head gasket, but they changed gaskets w/o changing tq values. not positive on it, but thats what a few of the threads and general conjecture led toward.

anyway, if its stock and you just want to up the tq, just torque to 72lb ft of tq, no back off. just tighten them in sequence to the higher value.

stock is 58lbs. when i first started getting into these motors i was surprised, my SBC was 65lbs with 5 bolts per cyl and less compression and better HG. 58lbs always seemed low to me from the start...

ps, have fun at lemons! ive always wanted to do it, almost took my old v6 camaro last time!
