Hey Grumpy, you sure started a pretty long thread!
Most of it is correct, and your replies show you are on the right track too.
-Yes, they say those bolts are only one use, but I have re-used them in
D-15 motors with NO problems. IF you have a problem it will be when the
threaded portion breaks off on the final torque. If that should happen,
your $16 ea will be well spent.
Run a tap into each of those head bolt holes. I've pulled out LOTS of
crap from the bottom of a hole that would have screwed up torque values.
Engine oil on threads?? Forget it! I saw an interesting demonstration by
an ARP guy torqueing fasteners with oil and assembly lube. The oiled one
creaked as it was torqued. The other one was quiet, and torqued
smoothly. ARP assembly lube is $15 for a tube but it will last a long
time. I also use nev-r-seize too, and it works well.
I would worry more about the rod bolts. THESE are the ones that snap
when re-used and should be checked carefully.
