S/R TORQUER

Cast Iron Heads

Small Block Chevrolet

An improved replacement for the factory Chevrolet 327-350-400 cylinder heads, World’s exclusive S/R Torquer series features 170cc intake runners and can provide up to a 30 horsepower increase over most OEM castings. Note, however, that these heads are accepted by many racing associations as “stock,” and are 50-state emissions legal. S/R Torquer heads accept early and late model accessories. The exhaust valve seats are hardened to provide compatibility with unleaded gas. The S/R Torquer heads are available in 67cc and 76cc versions for engines up to 1986 and 76cc for 1987-on applications. They are designed to use 2.020" intake and 1.600" exhaust valves, and work well in engines from 302 to 400 c.i.d.
