Replacing the now fresh head on a 95 606, get the bolts down to around 25 ft lbs ( 35 nm) and leave them there for a day or so. Final torque this am.

Go to 35 ft lbs ( I know I am using switching units as the final TQ spec in the FSM is a 90 degree something or other...) no problem, go to 45 ft lbs, and #1 take a bit too much to clic the wrench, I notice, and I drive on.

Go to 55 ft lbs. That would ahve been a full 90 degree turn. #1 wont clic, and I can turn it way more than 90, 180, stop. bolts gotta be bad and stretching too much, swap in a fresh head bolt, bring it to TQ in two steps only, To 55, same deal. ??? Kick myself for not spending the $$$ for a metric tap/die set and chasing those threads in the block while the head was off. doh. cleaned them, they looked fine.

Anyway, long story short, final TQ was 73 ft lbs. More than just the #1 bolt would not clic the wrench, so I used 90' degrees as a guide. The few were clustered in the center of the block near #1. Most bolts did literally turn 90 degrees twice from the inital 35nm to get to around 68-72 ft lbs. There are four that wont clic the TQ wrench, and I dare not spin them any more. Only "stretch" bolts I've ever dealt with were Chevy 427 L88 boron rod bolts when I was a kid, last century!

Just reinstalled the cam tray. Guide pins in ( upper is near FUBARd).

Am I saying a Hail Mary here?

THNX for ur opinions.
