I was going to use the FELPRO torque-to-yield set (ES72173), but there have been a few instances (maybe very few...) where they have broken off during tightening.

I think you could get away with either fel pro or OEM TTY bolts. There have been cases where people will reuse TTY bolts and also run boost under them, BIG NONO. and the motor runs perfect. you can use arp because they are not torque to yield so they are reusable. what year Is your engine? depending on if its a post 2004 you can get away with almost any set of LS style arp bolts. If its a pre 2004 (when the outside bolts where longer in the middle row) then you'll have to dig further for those. I'd give ARP a call and see what they recommend and if there's a better set you may need.
