[V8] Head bolts

Jason,

I'll have to check to see if they mention it in the V8 manual.  Easy way to
check is the design of the actual bolt.  The  torque-yield bolts have and
additional screw thread that is reverse of the actual threads that comprise
the shank and with a much wider spacing, IIRC.  Regular headbolts just look
like long, beefy bolts with long smooth shanks until the business end
threads appear.  Not sure, but I think the torque-yield bolts have attached
washers, whereas the other non-torque-yield bolts have separate (removable)
washers.
