These cylinder head bolts from the High Performance series are a premium replacement for OEM fasteners.
They feature a wide area flanged head and reduced wrenching hex that eliminates the need for valve train removal to facilitate cylinder head retorquing.
The bolts are rated at 180,000 psi, which is 15% stronger than Grade 8 hardware, and they come complete with hardened parallel-ground washers.
This kit is designed for select Chevrolet big block applications (late Bowtie aluminum, World Prod.
Merlin, Iron Dart, Pro-1, Pro Top Line).
