Upgraded Grade 12.9 Headbolts For 24 Valve Cummins

Here’s a good cheap upgrade for a mild/tow build where you don’t need head studs but don’t want to reuse the factory head bolts. The common rating people have established is 550hp for them, but depending on your combo they could do more ( such as high rpm and low torque)

In the box is 27 bolts with washers, that’s a full set plus 1 extra in the event that you over torque them.
