Chevy Small Block Angled Plug Hydraulic Roller Assembled Aluminum Cylinder Head

• 198cc intake runners improve Small Block Chevy airflow

• Hydraulic roller springs support modern cam profiles

• Angle plug design helps improve header clearance

• Fully assembled aluminum construction saves installation time

Upgrade your Gen I Small Block Chevy engine with a fully assembled aluminum cylinder head designed for hydraulic roller camshaft applications. Featuring 198cc intake runners, 64cc combustion chambers, and 2.020" intake / 1.600" exhaust valves, these performance cylinder heads are engineered to support increased airflow, improved throttle response, and greater horsepower potential in street performance, muscle car, hot rod, and street/strip builds.

Designed for modern hydraulic roller cam combinations, these Small Block Chevy aluminum heads provide the airflow capacity needed for performance-oriented 350 Chevy, 383 stroker, and other Gen I SBC engine combinations. The optimized runner and combustion chamber design helps improve cylinder filling and combustion efficiency, supporting stronger torque production throughout the RPM range.

The angle plug configuration can provide improved spark plug accessibility and additional clearance in many header combinations commonly used in high-performance applications. Lightweight aluminum construction helps reduce front-end weight while dissipating heat more efficiently than traditional iron cylinder heads.

Delivered fully assembled with valves, hydraulic roller valve springs, retainers, locks, and seals, these cylinder heads help simplify installation while providing a solid foundation for performance street engines, weekend racers, muscle car restorations, and custom Small Block Chevy builds.

Whether you're building a hydraulic roller 350, a 383 stroker street machine, or a performance-focused Gen I SBC engine, these assembled aluminum cylinder heads deliver the airflow, durability, and performance potential serious enthusiasts demand.

Cylinder Head Technology
Designed with 198cc intake runners, 64cc combustion chambers, and 2.020" intake / 1.600" exhaust valves, these assembled aluminum cylinder heads are engineered to improve airflow and combustion efficiency in Gen I Small Block Chevy applications. The angle plug configuration helps improve spark plug access and may provide additional clearance in many performance header combinations. Hydraulic roller valve springs make these heads an excellent choice for modern hydraulic roller camshaft builds.

Performance Benefits
