ARP 12 point base nuts x 4
ARP washers x 4
Head gasket

Includes our Maxlock 304 stainless head studs with washers and ARP 12 point flange nuts as well as a stock bore head gasket. Using a stud/nut instead of a bolt makes a tighter, stronger seal. These studs pay for themselves over time! Everything is new in the original packaging and the original manufacturer’s warranty applies*
