Alberta, -are you absolutely sure the 12mm mains aren't 2-pass 55lb/ft then 90 degrees?

I seem to have some conflicting information, -just want to be sure.

BTW, nice work man!

Just looked in a GM service manual to check, and You are right. I missed the last row. :banghead:
Typed most of it up last night at midnight. I quess I should proofread better

NOTE: Alberta Redneck edited/proofread everything and made the changes required. The information that you now see is correct. --JiFaire

If a Mod could delete post 3,4,5, & 6, that would be great. I fixed them up, made all the editing the same, and combined what was missed. Thx

-- Done. The incorrect information is removed. -JiFaire

I'm looking for the head torque spec for 6.5 turbo diesel with studs and nuts. Is there a certain way to torque these and do I add washers? Your help is appreciated.
