Cylinder Head Bolt Kit by ARP®. The engineers at ARP spent quite a bit of time developing these highly effective, unique oil pan studs. They’re designed to make it as easy as possible to install a pan and seal it properly. You’ll note that the studs have a radiused bullet nose that serves to locate the pan rails, then allow the nuts to be easily installed without the worry of cross-threading. For those who prefer bolts, ARP’s got you covered, too.
