hey I represent that knuckle dragging, dirty finger nail remark! I prefer OEM TTY. They are way cheaper (that makes a difference when you have 4 engines like I do) and every bit as effect if done right.OEM bolts, being torque to yield, are of course for the dirty, unwashed, knuckle-dragging masses...not the alpha cognoscenti that of course populate this site!
It was really funny watching the YT video a few months back from Nathan’s garage when he couldn’t figure out how to do TTY OE bolts on his S85 so he threw them out and went with BE’s ARP bolts. Some people only know how to use clickers....
He also used random Orings, then talked about how he didn’t skimp or cut corners.
