Such as, the case with the head bolts. Thankfully ARP produces cylinder head stud kits that are designed for the real world of diesel competition. These studs are thread-rolled to Mil-S-8879 specifications for increased strength and precision center less ground for accuracy. They are built specifically for high performance diesel applications and are highly recommended for engines running 45 psi and higher boost, or those with nitrous applications.
