Car runs but white smoke from tailpipe (long)

Finally got my '91 9kt cylinder head back on. Installed new Elring head gasket and new Elring head bolts, torqued to specs plus 90 degree tightening angle. The engine runs but it appears I'm getting coolant in at least one cylinder. White smoke from the tailpipe. Checked to see if my other car does the same thing on this cool evening, and it doesn't.
I noticed a funny thing. After tightening each head bolt through 90 degrees and waiting a few hours, I checked to see what the torque on each bolt actually was. Since you start at 59 ft-lbs and then add 90 degrees, they should all be the same, right? Well, the back-most bolt at cylinder 3 was looser, showing only about 80 ft-lbs, whereas all the others were about 130. Cylinder 3 was the one I had the coolant in, prior to getting the head re-surfaced.
Any chance the head will seal itself with running the engine? Should I put a bit more torque on the head bolts? I can't believe this has been so difficult. If I can't get it right this time, I think I'll take it to the (gulp) dealership. Thanks.
