Fitment: Fits 1960-1986 Small Block Chevy (SBC) V8 engines, including 302, 327, 350, 383, and 400 cubic inch models Straight-plug design: No block modifications needed; works with original SBC ignition systems (no Vortec-style intake manifold compatibility required) Description: High-Performance Cast Aluminum Cylinder Head for SBC Engines (Straight Plug) – Fits 1960-1986 Chevy V8 Designed for 302/327/350/383/400 small-block Chevy (SBC) engines up to 1986, this straight-plug cylinder head delivers street performance, stroker kit compatibility, and mild racing capability. Lightweight cast aluminum cuts engine weight, boosts airflow via 200cc intake runners, and optimizes combustion with 64cc chambers—ideal for Chevy V8 owners upgrading power without sacrificing reliability. Product Details - This item is not solad as a pair, this is a single cylinder head. High-Performance Advantages Street Performance Focus : Tuned for 1500-6500 RPM use—paired with high-flow intake, mid/high-lift camshaft, or performance manifold, it delivers noticeable horsepower gains for daily-driven SBC 305/327/350/383/400 builds Stroker Kit Ready : 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 choice) Mild Racing Capability : Stable power output (5500-6500 RPM) with mechanical/hydraulic roller cams (flat tappet/roller); upgradeable 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 : Far 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 : Square intake/exhaust ports + 2.020" intake/1.600" exhaust valves maximize airflow; 23° valve angle ensures efficient combustion Key Notes Bare-cast version: Does not include valves, springs, seals, or assembled components (requires separate hardware 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
