An easy way to gain 20 to 40 Horsepower on any Small-Block Chevrolet V-8 is by installing a set of Vortec cylinder heads. These value priced cast iron cylinder heads use modified combustion chambers and high velocity port technology to provide improved performance. Vortec cylinder heads significantly outflow non-Vortec service replacement cylinder heads and earlier OEM cast iron heads. These cylinder heads are ideal for applications up to 350 Horsepower, but they require Vortec specific intake manifolds.
