SBC 305 Vortec Cylinder Head - Bare 96-up

The EngineQuest SBC 305 Vortec Cylinder Head Bare 96-up is a high-flow iron casting engineered for small-block Chevy engine builds seeking improved breathing and combustion efficiency. This bare cylinder head delivers 170 cc intake runners and a 58 cc combustion chamber, making it suitable for street performance and racing applications where cylinder head flow characteristics directly impact horsepower and torque output.

The 1.840-inch intake valve and 1.500-inch exhaust valve configuration is optimized for small-block Chevy specifications, allowing maximum fuel-air mixture flow during the intake stroke while maintaining proper exhaust scavenging during the power cycle. The straight-plug design simplifies ignition system integration and reduces installation complexity. Cast iron construction provides thermal mass and durability under sustained high-RPM operation, critical for engines that see track time or heavy-duty service. At 53 pounds, this is a production-weight head suitable for bolt-on installation onto existing small-block Chevy blocks.

Engine builders and performance enthusiasts restoring or modifying 1996 and later small-block Chevy platforms choose this head to upgrade from stock castings without the cost of fully ported or billet alternatives. The Vortec platform compatibility makes this a direct replacement or upgrade path for trucks, SUVs, and performance vehicles using the classic 305 cubic inch engine. Whether for daily-driven horsepower gains, weekend cruiser builds, or restoration work, this bare casting provides the flow characteristics needed to unlock additional performance from carburetor or fuel-injection equipped platforms.
