SBC 165cc I/E Head 67cc Vortec 1.94/1.50

The DART SBC 165cc I/E Head 67cc Vortec 1.94/1.50 is a bare iron cylinder head designed for serious small-block Chevrolet performance builds and restorations. It is ideal for engine builders and mechanics looking to enhance flow efficiency and optimize combustion chamber performance.

This casting features a 67cc combustion chamber, 1.94-inch intake valves, and 1.50-inch exhaust valves, which optimize charge motion and scavenging across the RPM range. The 165cc port sizing provides superior flow characteristics compared to earlier small-block castings while maintaining the structural integrity necessary for reliable street performance.

Engine builders will appreciate the bare iron construction that allows for custom porting and modifications to suit specific displacement and compression needs. This head is particularly beneficial for stroker builds, street performance engines, and competition powerplants.
