:banghead:I have gotten conflicting torque specifications and as a result it may have caused me to strip out one of my head bolts. I have a '92 Deville w/4.9 of coarse aluminum block. I have gotten different info concerning the torque on the head bolts. One source (a Hay's Manual) says 1st 38 ft/lb, 2nd 68 ft/lb and bolts 1,3,4 3rd 90 ft/lb. I actually started wrong by looking at the wrong chart and did 1st 35, 2nd 48 and then procedid to do the rest at 60 ft/lb but the first bolt stripped at that setting before reaching 60. Was my block weak already or is the chart on page 2B-2 of the Hays GM Cadillac Deville 86 thru 93 book wrong listing the setting for 1,3 and 4 @ 90 ft/lb? Could someone tell me what the current specs directing cadillac mechanics are? And also I don't have $350 to purchase an 11 x 1.5 timesert kit. Someone else told me to use a 12 x 1.75 heli-coil kit for the stripped out number 1 head bolt. I could really use some expert advice here please, and thank you!
