Pro Series Head Bolt Kits
Available with a reduced wrenching hex or 12-point, wide area flanged head that eliminates valve train removal for cylinder head retorquing. High-performance bolts are 180,000 PSI (15% stronger than Grade 8), and Pro Series bolts are 200,000 PSI. Kits are complete with hardened, parallel-ground washers. Most applications include undercut short bolts.
