ls stud kit gen 3. 3 stars because the stud caps are pretty thin. no directions, used arp bolt lubricant and torqued studs tp 22 ft lb. and then torqued caps in 3 steps up to 80 ft lb. caps made me nervous and the 12 point socket machining wasnt great but they are holding the headgaskerts fine so far. next time ill spend an extra $100 for arp bolts

Don't try to torque these to 75 ft lb, I broke one and had to remove the head to remove it. I had to use cobalt drill bit and screw extractor. I wouldn't go past 70 ft lb.

Got my package, didn’t need to open it for a few months as it was for another project. Opened it up and bolts broken. Can’t even return them. Also had markings of already been wrenched on. Not happy with what was delivered.
