No disagreement here. We stretch bolts all the time in the oil refinery to get consistent clamping loads. It's the method of choice for high pressure and large rotating equipment.

Head gaskets arrived today. I was advised on CHRF's Northstar forum to use head studs, which for an idiotic reason I didn't get ordered today... I'll have to wait until Thursday to torque the heads down. I'll set the heads in place, hang them with a couple of snug bolts and build the timing drive, seal up the bottom end/front cover and install flywheel/clutch tomorrow (@$$uming I can find my stash of 12.9 flywheel bolts). Thursday I'll see about getting the trans apart and the 3.94 gears installed. I already have a great grip and the short 2nd and 4th in it. I'll also have to find my stash of 12.9 ring gear bolts.

Got any spare flywheel bolts that would work on a spec AL flywheel? What is the reason Alan gave for using headstuds? I used them on my rodeck and never had a problem blowing gaskets with 800hp ( boosted ) on tap

Even if I can't find my stash, I'll have bolts. I ordered a box of 50 from Lawson. I'll mail you a set.

I was playing with the serpentine belt and I believe I've had my Eureka moment regarding how to fix the accessory drive. Now if I can just find the exact tensioner I'll need to make it work...

What was wrong with it?? I am using a smaller form factor alternator so I can get the dang thing out without alot of hassle if needed on the road

It was slipping at high RPM. It didn't have enough wrap on the crank pulley.
