STUDS vs. BOLTS

Studs also provide more accurate and consistent torque loading. Using studs ensures easier engine assembly, and proper alignment of both the cylinder head and gasket.

The ARP 134-5901 LS Main Stud Kit is perfect for that application!

Heres why: when you use bolts to secure the head, the fastener is actually being twisted while its being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously.

Install a stud in a relaxed mode never crank it in tightly using a jammed nut. Always install the stud hand tight! Then, when applying torque to the nut, the stud will stretch only on the vertical axis.
