Chevy SB Pontiac Brodix aluminum heads, raised intake, -10xz, RI, 12-Point Pro Series ARP 234-3704 cylinder head bolts.
Available head bolts feature a reduced wrenching 12-point and wide area flanged head that eliminates the need for valve train removal to facilitate retorquing of cylinder heads.
All Pro Series bolts are cold-forged to ensure molecular integrity, heat-treated prior to thread rolling and machining, and rated nominally at 200,000 psi.
ARP Pro Series head bolt kits are application specific – designed for use with typically competition only components.
These fasteners deliver superior strength and meet the ARP “ZERO defect – ZERO failure” quality standard.
Included with each kit are hardened and parallel-ground washers to ensure even load distribution and accurate torque readings.
All Pro Series head bolts feature a reduced wrenching hex or 12-point head and wide area flange to eliminate the need for valve train removal for retorquing of cylinder heads and permit the use of larger diameter valve springs.
Most applications have undercut short bolts that can help eliminate head gasket failures through providing more “stretch” to compensate for the additional compression of gaskets.
