E-210 Series Aluminum Cylinder Heads
The E-210 cylinder head for small-block Chevy engines provides race-level performance while maintaining full compatibility with OEM equipment. These heads can produce more than 500 HP from a naturally aspirated engine and even more from a forced induction system. The power created with the E-210 heads comes from large runners for increased airflow, larger diameter springs for higher lift camshafts and revised exhaust ports. All of these added features make the E-210 heads 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 needed to compete at engine speeds of up to 6500 rpm.
Note: Heads may not be used on engines with less than a 4" bore (262, 265, 283, 305, 307 c.i.d.) except with cams having less than .450" valve lift.
