Description:
High-Performance Cast Aluminum Cylinder Head for SBC Engines (Angled Plug) – Fits 1960-1986 Chevy V8
Engineered for 302/327/350/383/400 small-block Chevy (SBC) engines up to 1986, this angled-plug cylinder head boosts street performance, works with stroker kits, and suits mild racing. Lightweight cast aluminum cuts engine weight, while 200cc intake runners and 64cc chambers optimize airflow—ideal for Chevy V8 owners upgrading power reliably.
Product Details
-This item is not solad as a pair, this is a single cylinder head.
High-Performance Advantages
-
Street Performance Tuned: Optimized for 1500-6500 RPM use—pair with high-flow intake, mid/high-lift camshaft, or performance manifold to gain noticeable horsepower for daily-driven SBC 305/327/350/383/400 builds
-
Stroker Kit Compatible: 200cc intake runners + 64cc combustion chambers balance compression ratio for 383/400 CID stroker kits; no airflow restriction for large-stroke pistons (budget-friendly high-performance option)
-
Mild Racing Ready: Delivers stable power (5500-6500 RPM) with mechanical/hydraulic roller cams (flat tappet/roller); enhance performance via CNC porting, intake polishing, or valve upgrades for drag/bracket racing
- OHV & Gasoline - Engine Cylinder Head Advantage: Engineered with an OHV (Overhead Valve) design, it ensures efficient torque output at low - to - mid rpm, ideal for daily street driving in hot rods, street cars, and tow vehicles. Tailored for gasoline engines, its optimized combustion chamber enables high air intake capacity, supporting turbocharged or supercharged systems for mid - to - high rpm track performance, enhancing power delivery and fuel efficiency.
Design & Material Benefits
-
Lightweight Cast Aluminum: Significantly lighter than OEM iron heads—reduces front-axle load, improves vehicle weight distribution, and enhances acceleration/handling
-
Superior Heat Dissipation: Aluminum construction lowers engine operating temperature, minimizing knock risk (critical for performance tuning)
-
Optimized Airflow: 2.020" intake valves, 1.600" exhaust valves, and 23° valve angle (intake/exhaust) maximize airflow; 74cc exhaust runners complement intake efficiency
Key Notes
- Bare-cast version: Does not include valves, springs, seals, or assembled components (separate hardware required for installation)
- Entry-level performance: Ideal for street/stroker/mild racing use; not suited for high-rpm (6500+ RPM) or extreme high-flow racing builds
