What are the torque specs for m11 cummins on 1997 freightliner?

Well, that depends on what you're torquing down.

55 ft. lbs. (75 n.m.) for the injector hold down capscrew.
130 in. lbs. (15 n.m.) for the rocker cover.
35 ft. lbs. (45 n.m.) for the intake manifold.
20 ft. lbs. (27 n.m.) for the exhaust manifold.
For the head bolts, you'll torque them to 50 ft. lbs. (68 n.m.) for the first step. Then you'd torque them to 100 ft. lbs. (136 n.m.) for the second step. Then you'd rotate the bolts 180 degrees for the third step.

If there's something more you're looking for, you'll need to be more specific.
