225 slant head torque

All the older stock engines I ever worked on were to be torqued with dry threads. I only ran into lubed threads the first time I used ARP bolts.

BTW, my '62 FSM for the /6 says to torque to 65 ft-lbs in sequence. Then retorque by first loosening each bolt (does not say how much) and then torque it again to 65 ft-lbs, and do that in the same sequence for each bolt. That was in the days when the original steel shim head gakset was used. You may not need to to that with a newer composite head gasket. I would still re-torque after a few heat cycles since these are not torque-to-yield head bolts.
