ARP Pro Series Head Stud Kit (Honda B20B with B16A Head / LS-VTEC) | Niced Up

Obtaining optimum cylinder head-to-block sealing is critical in high-output small-displacement engines employing high compression pistons or power adders like turbochargers, superchargers, and nitrous oxide. The ARP Pro Series Cylinder Head Stud Kit (Part # 208-4306) is engineered specifically for Honda B20B and B20Z engine blocks utilizing a B16A or B18C VTEC cylinder head (LS-VTEC and CRV-VTEC hybrid conversions).

Manufactured from premium 8740 chrome moly steel heat-treated in-house to 190,000 psi tensile strength, these studs are thread-rolled after heat-treating to provide 1000% better fatigue strength than studs threaded prior to heat-treating.
