BBC OP Cylinder Head 280 CFM 113cc Assembled

The BBC OP Cylinder Head 280 CFM 113cc Assembled from TRICK FLOW represents a fully prepared, bolt-on engine component engineered for serious performance builders and restoration specialists. This assembled cylinder head delivers the foundational breathing capacity required for big-block Chevrolet platforms seeking measurable gains in volumetric efficiency without requiring extensive machine work or custom porting. Law enforcement and tactical vehicle builders rely on such high-flow heads to achieve responsive powerplants in support vehicles and duty rigs where reliability and incremental performance upgrades are non-negotiable.

TRICK FLOW's engineering prioritizes flow dynamics across the intake and exhaust port passages, with the 113cc combustion chamber volume optimized for efficient fuel mixture burn and reduced quench distances. The 280 CFM specification indicates the head's measured flow capacity at 0.500-inch valve lift—a benchmark metric that reflects real-world intake and exhaust scavenging rates essential for sustained horsepower delivery. Pre-assembled construction eliminates guesswork in valve train setup, rocker arm geometry, and spring pressures, ensuring that installation focuses on proper head gasket selection, torque sequencing to specification, and coolant system integration rather than component assembly or valve lapping.

Builders upgrading stock or semi-prepared engines—including those supporting armored or upfitted platforms—benefit immediately from the plug-and-play integration this assembled head provides. Compatibility with big-block Chevrolet platforms (BBC/Mark IV engine families) is assured when proper manifold sealing surfaces, dowel pin alignment, and fastener torque specifications are observed during installation. The 46-pound assembly integrates with existing exhaust headers, intake manifolds, and cooling systems when dimensionally verified against your specific engine block and ancillary components; professional machine shop verification of deck height and surface finish is recommended to ensure optimal gasket sealing and long-term reliability in demanding duty cycles.
