Description

World’s S/R cylinder heads are the preferred alternative to expensive OEM castings or junkyard rebuilds. These heads are designed with extra-thick decks and walls for improved reliability as well as equipped with hardened steel exhaust seats that are compatible with today’s unleaded gasolines. They are machined for screw-in rocker arm studs for extra durability. 58cc chamber is suited for 305 cubic inch SBC. S/R Cylinder heads are fully 50-state emissions legal and because they are an OEM replacement head, they are legal for use by many oval tracks and race Sanctioning organizations.
