SBC SHP Cylinder Head 180cc/72cc SP - Assem.

The DART SBC SHP Cylinder Head 180cc/72cc SP assembled unit is a Small Block Chevy performance component engineered for builders and machine shops targeting street and strip applications. This aluminum casting delivers the flow characteristics and chamber geometry necessary for elevated horsepower targets while maintaining the reliability and straightforward installation that experienced builders expect from modern performance heads.

The 180 cubic centimeter intake port and 72 cubic centimeter combustion chamber define this head's intended powerband. The 2.020-inch intake valve and 1.600-inch exhaust valve configuration supports efficient cylinder filling and scavenging across the RPM range typical of carbureted and port-injected SBC platforms. The 1.550-inch valve spring diameter matches common aftermarket spring assemblies, and the straight-plug configuration simplifies spark plug access and head gasket selection. Assembled construction means valve seats, guides, and springs arrive installed and ready for block mounting, eliminating machining delays and reducing the total engine assembly timeline.

This head suits engine builders, restoration shops, and serious hobbyists building carbureted or EFI Small Block Chevy engines for highway cruising, weekend track duty, or bracket racing. The moderate intake volume and chamber size optimize mid-range torque delivery, making this casting a practical choice for street-driven vehicles where driveability matters alongside peak power. Compatibility with widely available SBC gaskets, fasteners, and accessories keeps parts sourcing straightforward.

DART's position in the performance cylinder head market reflects decades of casting refinement and OEM supplier experience. The SHP series occupies the value-conscious tier of performance heads, delivering measurable flow improvement over stock castings without the premium pricing of top-tier competition heads. For builders balancing cost and performance, this assembled head eliminates secondary machine work and valve installation labor, reducing overall engine buildout complexity.
