SBC 225cc D/S Heads 68cc 2.08/1.60 Assembled

The BRODIX SBC 225cc D/S Heads 68cc 2.08/1.60 Assembled represents a high-flow cylinder head solution engineered for small block Chevy platforms demanding maximum intake and exhaust efficiency. This is a complete, ready-to-install assembled cylinder head pair (MPN 1321001) designed for builders and engine shops seeking proven performance in street, strip, and marine applications where displacement and breathing capacity directly translate to horsepower gains.

The 225cc intake port volume combined with a 68cc combustion chamber creates the flow architecture necessary for naturally aspirated and boosted SBC configurations targeting peak cylinder charging. The 2.080-inch intake valve and 1.600-inch exhaust valve sizing optimizes the breathing window for mid-range and high-RPM power bands. The 1.550-inch springs manage valve float and control resonance across the operating range. Angle-plug configuration supports modern ignition systems and combustion chamber geometry optimization. Aluminum construction delivers the weight savings critical in performance engine packages while maintaining structural integrity under sustained high-load conditions.

This cylinder head pair addresses the needs of engine builders developing street performance engines, race-prepped vehicles, and marine powerplants where cylinder head selection directly impacts dyno results and real-world acceleration response. Customers integrating these heads into existing SBC blocks require a cylinder head with documented port flow characteristics, valve sizing matched to intended displacement and boost levels, and assembly quality that eliminates guesswork during engine build. The assembled configuration reduces installation lead time compared to bare castings requiring machine work and valve job specifications.

BRODIX cylinder heads are recognized in the SBC performance community for aggressive port geometry and quality aluminum casting. The 225cc/68cc specification positions these heads in the higher-displacement, higher-revving segment of the small block platform, suitable for 400+ cubic inch engines and forced induction applications. Verify gasket surfaces, mounting hole alignment, and valve train clearance compatibility with your specific block, intake manifold, and carburettor or fuel injection system before final purchase.
