FITS: SMALL BLOCK CHEVROLET, SBC WITH LARGE JOURNAL -- 4 BOLT MAINS ARP recommends the use of main studs over bolts whenever possible for several key reasons. First the ability to obtain more accurate torque readings because studs don't "twist" into the block. All clamping forces are on on axis. By the same token, there is less force exerted on the block threads, which contributes to improved block life.
Finally there are factors of easier engine assembly and proper alignment of caps every time.
