I've got a '91 LWB that I put head gaskets on about 5k mi. ago. At the time, I was unaware of the TSB with the updated head bolt torque specs, so I used the old ones - 72 lb./ft. in two steps. Put it together and everything is fine, works great. I'm going to have to remove my upper intake soon to replace the pcv valve and to fix a leaky hose (things I'd have liked to have done before), so that'd be a good time to address the head bolt torque, which needs to be 80 lb./ft. Has anyone had a problem with retorquing the head bolts after use? I didn't replace them when I did the head gaskets, but I measured them and they were all the same in length and condition. I don't see a problem with it as they aren't torque-to-yeild bolts, but I wanted to be safe. I did a search but I didn't come up with anything.
