crazy torque sequence

I do A LOT of engine work and some of the ones i repair have two smaller torque steps and then back off completeley and then retorque to a third and then + 90 degrees. (TTY) Insane. Many auto manufacturers have there own ideas and even for the sake of argument follow the manufacturers standard unless using a non oem design and it specifies differently.Reality is stranger than fiction.

I like that process but it only works on what it is designed for. I had sbc on my mind when I started the poll and I might should have kept the question to that but it is good that these other applications come up. SBC has short bolts on lower row what tty wouldn't work for; at least I don't imagine they would have that spring in a short length.
But man, if there was TTY for SBC and many older designs it would settle this question once and for all, in my book. TTY felt weird the first time. My son re-states over and over when the subject comes up; that head bolts are simply springs, and TTY with the advanced metallurgy, allows for a super spring that follows down.. I don't think I ever understood re-torque completely until that revelation soaked in. I never trust the small block or anything old to still have the same torque on it next week unless I check, Peace o mind. Duntov Ps Hey from South Carolina 99 degrees today
