When torquing the head bolts on my M104 I made a little chart in my notebook that had the bolt # and the three torquing steps (56 N-m, 90 deg, 90 deg). I wrote a number on the head next to the bolt with a Sharpie, then I made a check mark in the book as I completed each step for each bolt because all 14 bolts get tightened in sequence for each step. I used a 2' long snipe on the breakover for the last 90 deg step and it wasn't too bad. The hard part is watching the angle gauge while applying mustard to the snipe to make sure you don't over or undershoot the angle.
The manual is pretty specific on the cam install procedure and it says exactly what Larry recommends, telling you which bolts to tighten on what cam bearing cap.
I had my head rebuilt by Metric Motors in LA. It was $1200 OTD. They had to do a couple weld repairs for corrosion damage and all my exhaust valve springs were out of spec. I had one pitted exh valve that had to be replaced. I also sent them my cams to mike and they cleaned and reassembled the cam advancer mechanism on the intake cam.
Actually the most time-consuming part of this whole job has been the incessant cleaning. Clean the carbon off the piston domes. Chase the head bolt threads and clean them out. Clean all the oil mess off the motor and from under the car from the leaky head gasket. Clean all the crap out of the water jackets (you wouldn't believe what was in there). Clean all the oil out of the upper and lower intake manifold. Clean the throttle body. Clean clean clean. :-) Thanks! Pete
