I know the long time builders have successful methods they have used over the years, so I'm sure some will chime in. Is it a Felpro composite? Did they come with a recommendation. More importantly regardless of 80 or 85, I think you want to strive for the same tension on each stud. Make sure you can get a clean straight pull on each fastener before you start. I would pull each one to see if they break torque, then go back through and back off 1/8th of a turn, then pull to final torque, follow the factory sequence, cant say I have more than a couple evolutions, so try to get some input from some of the more notables on the board. A lot of variables and uncertainty in fastener torqueing, try to minimize the variables.
