    World's SR Torquer provides up to 30HP over stock heads. The S/R Tourquer cylinder head is the preferred performance 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 unleaded gasolines. They also come with screw-in rocker arm studs for extra durability. Needless to say, the S/R Torquer is substantially more durable than OEM castings. They feature a a larger 2.02 Intake Valve and a 1.6 Exhaust Valve. Valve cover rails have been raised and carefully machined to eliminate oil leaks and the heads can accommodate either early style perimeter or late model center bolt valve covers.
