That's an interesting thought, thanks

Hi folks, I am new to the forum and am researching head bolt torque procedure. I am re-using head bolts and I want to know if I need to do the initial 22 then 51 ft.lbs and back off 180 twice. Is that not meant to pre-stretch NEW bolts? Can I not go to 25 and 11 ft.lbs and the 90 deg 90 deg and get the same results of near 90 ft.lbs
