Update: I pulled the intake off tonight, and checked the top row of nuts. I put a click and beam style torque wrench on the nuts and pulled -- the nuts did not budge at 65 ft lbs with either wrench. I loosened a few just a tad and retightened, and they did not move beyond where they were. I'll pull the cam tower this weekend. If the wet nuts don't budge either, I am torn between (a) tightening them up to 80 or 90 ft lbs, or (b) pulling the head, checking for flatness and, if flat, trying a set of factory studs. I'll be assembling and installing a 3L over the next few months (pistons ariving next week), so if the deck is not flat and I need to pull the motor, I am not likely to reinstall it -- which has me leaning toward giving higher torque a try.
I also snapped off the blue radiator plug while draining the coolant. Anyone know if Parts Heaven has them on the shelf? If not, I may need to summons the mighty power of Rennlist to score a plug over the weekend.

Tom, since you have the intake off it may be worth it to take a torque wrench the the head nuts that are exposed (the ones not buried under the cam tower). Just check to see if they are still at the same torque.

Anyone know where I can get a precision straight edge locally?

I know you're all on the edge of your seats, so here's my update. I pulled the cam tower this morning. Although the nuts under the cam tower all clicked-off with the wrench set at spec, when I backed them off a tiny bit (say 5 degrees) and re-torqued, they clearly turned further tight (say 15-20 degrees more) in order to get back to spec. I'm hoping I just didn't wait long enough before re-torquing last time, and the HG compressed a bit more. I'm going to tighten them a bit beyond 65 ft lbs too. Here's to hoping!
