The new E-210 cylinder head for small-block Chevy engines provides race-level performance while maintaining full compatibility with OEM equipment. It features larger runners for increased airflow, revised exhaust ports and larger diameter springs for higher lift camshafts, making them ideal for a spec series racer and larger displacement engines. The exhaust port flange is in the stock location to allow for the use of off-the-shelf headers and hardware, while the enlarged valves and ports support the power need to compete at engine speeds of up to 6500 rpm. The E-210 cylinder head is capable of supporting more than 500 naturally aspirated horsepower, and even more in forced induction applications.
