Works on 06 5.3L LS

Installed these on my 06 5.3L LS and worked great. Follow torque specs given. It was something like 25ft, 55ft & 85ft lbs. No stretch specs listed.

Seems to be good quality

Time will tell, but they look and feel good quality, torqued without any issue, seems like a good middle ground between stock bolts and arp studs

Nice Quality Kit

I used arp torque specs at 75 final.... 25 on the small ones, none broken.. be sure you have washers on the right side, plenty of grease to completely coat all threads and between washers and bolt heads with leftover, I think it was arp or jegs bolts that called for 75, seen people say 70 is plenty so I'm good with 75

Update to my previous review, Very Very impressed, got a email a day or so ago with a refund and new head bolts shipped out and they showed up today, the Xotic performance team does a incredible job taking care of there customers, 100% buying from them again
