670 torque specs

[r9559]

Helping a friend rebuild the top end on a 98 670. What are the torque specs for the head and cylinders? The coolant wasn't drained out of the motor before it was taking apart. When I saw it the crank case was full of antifreeze and it was been like that for 2 months. Is it safe to put it back together without replacing the crank bearing?
Thanks

You need to clean all the water out of the bottom end, It dosn't matter if its been there 5 minutes or 5 months, the water will rust the bearings and turn into hell... Trust me, you don't want any moister down their... Next time drain the water out 1st then you don't have to worry about any future problems with the bearings...
