To ensure proper sealing of valve covers, ARP manufacturers a variety of special application-specific bolt and stud kits. Many professional engine builders prefer to use studs because of their ability to properly position the gasket and guide the cover into position.

ARP offers studs and bolts in a choice of chrome moly steel with black oxide finish or polished ARP stainless. You have a choice between convential hex head bolts and nuts or compact, 12-point designs. The nuts feature a wide base for better load distribtution and sealing, while the compact head is more easily accessed. Stud Kits come complete with nuts and washers, while bolt kits are shipped with required flat washers.
