3.7 head replacement

I try to do light repairs to vehicle since I was forcefully retired from the automotive business. Anyways a friend brought over his 2010 Liberty for a tuneup and instead found a blown head gasket. Pulled head while at top dead center compression stroke. Had to replace head due to warpage. Number 2 by the way was the one pumping water but for some reason after pulling head number 3 cylinder looked like it swallowed a bolt. the head was pounded but piston was perfect. Must of had a head replaced at one time with a bad head. Yea I know.Ok anyways online there is a torque specs for the head. one spec is for 20lbs on all 13mm bolts then 1/4 turn. It was missing the other 1/4 turn part. You have to do it twice. I also did not have to pull the timing cover to perform this procedure. For getting the upper tensioner back in you have to retract the oil tensioner. I just placed a long hose clamp end ontop of the tensioner and inserted the tensioner once in place just pulled the hose clamp strap out. Easy.
