I just got done reringing my motor and I put a MLS headgasket in. Now I was up underneath the car today and seen a very little bit of oil on the back of the motor. I traced it up to the HG. Now here's the thing, when I torqued the bolts down, I only torqued them down to factory specs, which I think is like 70 or 75. Is this wrong?

FSM says the following. INSTALLATION SERVICE POINTS CYLINDER HEAD BOLT (1) Cylinder head bolts should be carefully examined before reuse. If the threads are necked down, bolts should be replaced. Necking can be checked by holding a scale or straight edge against the threads. If all the threads do not contact the scale, the bolt should be replaced. (2) Before installing the bolts, the threads should be oiled with clean engine oil. (3) Tighten the cylinder head bolts in the sequence shown in figure. Using the 4 step torque turn method, tighten according to the following values. * 1) Tighten center fasteners 1 thru 6 to 33 Nm (25 ftlbs.). Then outer fasteners 7 thru 10 to 27 Nm (20 ft.lbs.). 2 ) Tighten center fasteners 1 thru 6 to 67 Nm (50 ftlbs.). Then outer fasteners 7 thru 10 to 27 Nm (20 ft.lbs.). 3) Tighten center fasteners 1 thru 6 to 67 Nm (50 ftlbs.). Then outer fasteners 7 thru 10 to 27 Nm (20 ftlbs.). 4) Turn all fasteners 1 .thru 10 90 turn. Do not use a torque wrench for this step.
Caution 1. Always make a tightening angle just 90 degrees. If it is less than 90, the hgad bolt will be loosened. 2. If it is more than 90; remove the head bolt and repeat the procedure from step 1.

These look exactly like the directions that I used. Correct me if Im wrong, but wouldnt this just be for a stock oem HG. I would think that for a MLS headgasket there would be different torque specs.
So the way it looks, I was just wrong in the post. Bolts 1-6 are torqued to a max of 50, with a 90 turn at the end, and then 7-10 gets a max of 20 ?, and a 90 turn at the end.

sorry but no it's not, the new specs and coming straight from Mopar is...6 center bolts, 25-50-50ftlbs, corners: 25-35-35ftlbs, then turn all fastners 1/4 turn or 90 degrees. i did this and no problems and i've been boosting hard.
