This ARP head stud kit fits Ford 351 R blocks with C-3 heads and uses undercut 12-point studs for head attachment. Packaged for that specific engine pairing, the 12-point undercut profile facilitates access in tight areas while delivering the complete fastener set required to secure the heads. It’s intended for direct replacement or upgrade where that head/block configuration is present.
