Too Short
These are too short by a long shot plus the studs are junk the wobble when you screw them into the block

lube after washer is on.
It is very important that head and washers are clean and oil/grease free. after washer is on the stud then apply small amount of arp lube to threads and bottom of nut. if you lube washer or head surface you will over tighten and possible break studs plus they will not have constant torque load.

Two sets failed!
I've bought 6 sets of these for GM gen3 and gen4 LS motor rebuilds/updates and out of that I have installed 3 of the 6. Out of the 3 sets installed 2 sets have failed now. The heads and block for each build was machined by a reputable shop, verified during build, all the bolt threads were chased, ARP moly lube was used on the studs/washers/nuts, the tightening pattern and procedure was followed and GM performance MLS gaskets were used. While removing the heads for a coolant leak into the crankcase on the most recent I pulled the records and verified final torque was done at 80ftlbs after letting them sit for 15 minutes at the previous spec. So setting the same torque wrench used to install them to peak and backing each one off the highest torque reading was down to 48.6ftlbs. They are not a 180,000psi bolt as stated if they stretched enough to drop 31.4ftlbs plus of torque after just 300 miles. Needless to say the other 3 sets I have will be going in the trash now! Spend the extra money on a better bolt/stud set!!

BEST CHEAP LS STUDS
31 PSI so far through a SBE gen 3.5 6.0, I'd say they are legit. torque 80ft lbs.
