1. High-Performance Advantages

• Street Performance Focus: Tuned for 1500–6500 RPM use, the EVIL ENERGY cylinder head pairs with a high-flow intake, mid/high-lift camshaft, or performance manifold to deliver noticeable horsepower gains. Ideal for daily-driven SBC 305/327/350/383/400 builds, these lightweight Aluminum SBC heads are a reliable upgrade for Chevy V8 engine heads, replacing stock SBC cylinder heads and enhancing performance in any SBC engine heads setup.
• Stroker Kit Ready: With 200cc intake runners and 64cc chambers, the EVIL ENERGY SBC heads balance compression for 383/400 stroker kits. This Aluminum Cylinder Head ensures no airflow restriction, making it a budget-friendly upgrade for Chevy V8 engine heads.
• Mild Racing Capability: The EVIL ENERGY SBC heads deliver stable power at 5500–6500 RPM with mechanical/hydraulic roller cams (flat tappet/roller). Upgradeable via CNC porting, intake polishing, or valve mods, these Aluminum Cylinder Heads are ideal for SBC cylinder heads, SBC engine heads, and Chevy V8 engine heads used in drag or 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.

2. 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-inch intake/1.600-inch exhaust valves maximize airflow; 23° valve angle ensures efficient combustion

3. 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
  
• This item is sold as a single cylinder head, not a pair.
