Small Block Chevy Dart-Buick Heads with undercut studs - Pro Series Studs

High Performance head bolts are available with a reduced wrenching hex or 12-point and wide area flanged head that eliminates the need for valve train removal to facilitate cylinder head re-torquing. All High Performance Series bolts are 170,000 PSI (which is 15% stronger than Grade 8) and kits come complete with hardened parallel-ground washers.
