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

The SBC 225cc D/S Heads 68cc 2.08/1.60 Bare cylinder heads from BRODIX represent a purpose-built solution for small-block Chevrolet engine builders seeking maximum intake flow and efficient combustion chamber design. These bare aluminum heads are engineered for high-performance applications where cylinder head flow dynamics directly impact horsepower, torque delivery, and overall engine responsiveness. Built on decades of racing and performance automotive development, BRODIX cylinder heads have earned respect among engine builders, fabricators, and serious enthusiasts who demand precision casting and flow-tested accuracy.

These heads feature a 225 cubic centimeter intake port volume paired with a 68 cubic centimeter combustion chamber, optimized for small-block Chevy platforms requiring responsive mid-range and top-end power. The 2.08-inch intake valve and 1.60-inch exhaust valve configuration allows superior fuel-air mixture delivery while maintaining efficient scavenging characteristics essential for street and competition engines. Manufactured from high-grade aluminum alloy, the bare casting includes angle-plug design for optimal spark positioning, critical for ignition timing reliability and consistent combustion across all RPM ranges. The pair weighs 57.33 pounds total, providing the lightweight architecture necessary for performance builds without sacrificing structural rigidity or thermal stability.

Engine builders preparing small-block Chevrolet short-blocks for street performance, bracket racing, or restoration projects benefit most from these heads' proven flow characteristics and aluminum construction. Installation requires proper valve train setup, gasket surface preparation, and integration with compatible intake and exhaust manifold systems—tasks best suited to experienced builders or professional machine shops familiar with SBC specifications. These bare heads ship without valves, springs, or pushrods, allowing builders complete control over valve train selection and tuning parameters specific to their engine's intended duty cycle and RPM envelope.
