      When putting pistons back in block – what do you torque the rod bolts – regular head screws?
      When putting the head on, there are regular head screws around the outside and two inner screws. Do you start with the inner two screws first and then work you way around the outside in opposite fashion – and what torque?

      How to you torque regular head screws??

        Regular headed screws?? Not sure I understand what you are referring to…
        In any event, torque the head bolts to 60-85 inch pounds, in three stages, working from the center out. Retorque after running and cool down…

                Sorry for the double entry. Can you tell I’m a rookie at posting pictures?
