World Products S/R cylinder heads make it easy to rebuild your engine affordably. They feature hardened steel exhaust seats compatible with unleaded gasoline, extra-thick decks and walls for improved reliability, tapped for screw-in rocker studs, and machined valve cover rails to eliminate leaks. The heads are available bare or assembled for a variety of applications. With the strength, reliability, and great price of these cylinder heads, there's no reason to bother with worn-out junkyard castings or new OEM castings—you can depend on World Products to help you do it right.
