I looking to put a new head gasket on my AC 2900 301ci engine and would like to know the correct ft-lb torque I need to put on the head bolts.

Up to 1973 the spec is 150 ft. lbs. and after that it is 165 ft. lbs. and the rocker shaft is 28-33 ft. lbs.

I usualy use the later spec no matter the year of the engine.

Thank you very much, one last thing? What is the correct bolt pattern for torquing these down.

There is an exact sequence in the manual but I don`t have it in front of me, I have always just started in the center,worked to the ends in an X pattern, and take the bolts down in three torque steps. i have never had a problem with thiss method.
