Chris, thanks for the response.

Yes, I did use 12 new bolts. I actually have two sets.

The only thing I can think of is that I didn't chase the threads on the head. I just dropped the oiled bolts in and torqued them in the correct order. Some are stretched tight, other can be tightened w/o squeaks or groans. Something must have caused a false torque reading on those bolts. I'm half tempted to remove them all and start other with the spare set. However if they don't torque up either, then I'm doubly screwed. Right now, They are all torqued up to about 90 lbs-ft. Only a few started groaning, about half are tight but not stretched, a few more could be torqued further.

Are there steel inserts in the block to take the bolts? I'm concerned that continuing to tighten bolts that won't groan is setting them up to strip out of the head.

Aside from some new oil seals for the Turbo-Block pipe, this is stopping me cold.
