Upgrading your stock head bolts is a necessity when building a upgraded motor.
Here are the Mazworx SR20 Head Stud Kit.
These are the correct length that will completely bottom out and provide extra clamping force needed. ARP2000 is capable of achieving clamp loads in the 215,000-220,000 psi range. ARP2000 is used widely in short track and drag racing as an up-grade from 8740 chrome moly in both steel and aluminum rods. Stress corrosion and hydrogen embrittlement are typically not a problem, providing care is taken during installation.

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.
