ARP 4.6L 2 & 4 Valve Cylinder Head Studs- (Hex Nuts)
Stock bolts and gaskets are OK for stock cars. But with high performance engines you want something better. Why take a chance on your new cylinder heads with cheap, mass produced bolts. Go with the best. Go with ARP.
Exact tolerances ensure that gaskets and cylinder heads just glide into position and align perfectly. ARP Head Studs are available with hex or 12-point nuts. These head studs are manufactured by ARP from premium 8740 chrome moly steel and heat treated to 190,000 psi. They are thread rolled after the heat treating process, which vastly improves their fatigue tolerance compared to studs threaded before heat treatment. High-quality, parallel ground washers included.
