Had these in my Mazworx built SR for under 1000 miles, had ZERO issues with them, just do not need them anymore. They have only been torqued one time and these do not stretch so they can be re-used. Visibly they look brand new, and come with everything included in the kit. These are much better than ARP studs because they fully engage the threads in the block and completely bottom out, ARP studs do not. Retail from Mazworx is $185.
$65 shipped FIRM
Here is what MAZWORX says about them:
Upgrading your stock headbolts is a necessity when building a upgraded motor.
Here are the Mazworx SR20 headstud 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.
Made from ARP2000 material
12 point
220ksi tensile strength
Straight shank/bullet ends from complete bottom out
Comes with (10) studs, (10) washers, (10) nuts and instructions.
