Hi Ken, I was sure I lost you for good, glad to have you back. As of torque, I couldn't get an answer from anyone so decided to use the torque out of my old 83 Diesel book--Nm 147.0 +29.4. I think this is a lot more than the 95 lbs? I wonder if I should to it over again?? Instead of acquiring more special tools, (already $250 bucks) I decided to have the valves done at the local machine shop. Got it back 2 days ago like new. Had I more time I could easily fabricate the tool you sent a copy of, but with the excessive heat we are having I lost all interest. The head is on now and yesterday installed all bolts (old bolts all to within 1mm of max) and torqued them to Nm 35. Next the 90 deg. it convinced me I never get another 90 out of them. Removed all bolts again and ordered new ones. Should be here on the 25th. I wonder if this normal, I mean applying so much stress? Of course the book says so and so do you it must be right. Just thought that the old bolts were already stressed out. Got the head installed with the exhaust manifold on, no problem. The real problem started getting the turbo back on. Believe me I gonna be the happiest guy when this ordeal is over and have the sucker running again. At the moment I'm composing a write up how I fixed the damaged head when I bored into the air duct in an attempt to remove a broken GP. If you send me your email address i will send you a copy when finished. I hate to expose myself more and more of a nut to whoever is reading this. Have a good day. I believe your location is much farther nord, you may have cooler temps. Cheers Hein

It takes a 27mm socket. Or did you mean the diameter and pitch of the threads?
