No one wants another head job when it comes down to head gaskets an studs. A lot of people complain about torque specs being to high or too low. With these bad boys set at a simple 45 ft lbs an then ending at 65ft lbs. I know I have the right clamping force to hold any properly installed head gasket. And they are fully seated unlike some other brands.

Purchased these after hearing horror stories about the other brand of head studs on SR20s, and I was extremely satisfied. No need to retorque them after a few miles of driving; I even called Mazworx to verify this. 10/10 customer service and product.
