676 Head Bolt Torque

[diggin dirt]

What is the head bolt torque reading for a endt 676, do i need to retorque after run in and are the head bolts reusable over and over.

Torque to 220 and as for as using old bolts it is ok if not piited or stretched and i dont know the length but i always run the engine foe maybe 10000 miles and retorque. I do not know what mack says to do any more but some here are dealer techs and can say. But for years i have always torque it when hot and i back off each bolt one at atime then retorque and you can mark them and you will always gain it the torquing so i say the clamping is better after a retorque. I think the newer gaskets is a no torque but to me the clamping is a gain in doing so. Free advice again.

I wouldnt fuss over a retorque but Glenns schedule is a good one if you going to 10000 miles is a good number.

Does it pay to re-torque the head bolts. I guess what I'd do is slightly loosen each head bolt, then torque it to spec.

Thoughts?
