Great affordable alternative to the big name company.
Great Heads studs for the money , Far superior to the first chinesium heads studs from a few years ago ! The tolerances are much closer and I never felt like the nuts were going to strip out before I got to the torque spec like the old ones .

They seem like they are well made. Worked perfect and easy to install on my lq9.

Meh, quality check of their product is poor.
Head stud was missing threads on one end, entirely smooth. Also, the hex key they include to install the studs into the block very obviously does not fit. Idk how you ship out a set of studs with a hex key and a stud that are all wrong. I probably wouldnt buy these again.
