SBC 180cc IK 180 Heads 64cc S/P Assembled

The SBC 180cc IK 180 Heads 64cc S/P Assembled cylinder head is a precision-engineered component designed for small block Chevy engine builders and performance enthusiasts who demand flow optimization and proven combustion efficiency. This assembled head pair eliminates the need for individual porting work, allowing engine builders to move directly to installation and tuning. Whether you're building a street performance engine, a track-focused small block, or restoring a classic Chevy power plant, these heads deliver the volumetric efficiency required for serious horsepower gains.

Manufactured from aluminum for weight savings and superior heat dissipation, the SBC 180cc IK 180 heads feature a 180 cubic centimeter intake runner package paired with a compact 64 cubic centimeter combustion chamber. The 2.020-inch intake valve and 1.600-inch exhaust valve configuration, combined with 1.470-inch valve springs, provide a balanced platform for both naturally aspirated and forced-induction applications. The straight spark plug design simplifies installation and maintenance while ensuring optimal ignition geometry for consistent combustion. These specifications are ideal for high-RPM applications where port velocity and flame travel efficiency are critical performance factors.

Engine builders tackling 350, 383, or 427 cubic inch small block Chevy platforms will find these assembled heads a time-efficient solution for both new-build and rebuild projects. The pre-assembled configuration eliminates valve spring installation variables and potential assembly errors, reducing labor time in the shop. Installation requires standard small block Chevy head bolt patterns and compatible intake manifolds—confirm your specific engine block generation for gasket and manifold compatibility. These heads pair well with modern fuel injection systems and performance camshaft packages designed for the small block Chevy platform.
