RestoCreations I don't agree with the torque numbers at all. These numbers are for Iron blocks and heads. I have been running a Shelby motor with 1020 felpro gaskets since 98. They where changed 5 years ago when I went to the stroker setup. 95 pounds on upper studs and 90 on lower with aluminum block and motor. You don't need any more unless you are running 14.0-1 compression. The one problem I have seen from too much torque is crushing of the area around the hole from washer and nuts. New car motors with aluminum motors run 65-72 pounds of torque. We have a torque to yield ,but comes out to this number. they also run stretch bolts for the heads. The other thing is that if you over rev the motor, the changes are better of blowing out a head gasket and not blowing out a block. Aluminum expands almost double compared to iron. This is why alot of motors lost head gaskets and intake gasket because of different expandsion rates both heating and cooling down.
It is more important to have clean surfaces and using RTV sealers, and maybe Hi-tac to seal motors and not have leaks. JMO and 30+ years of mechanic. 15 years student of FE motors. Rick L.
