SBM 190cc Cylinder Head Assembled

The Trick Flow SBM 190cc Cylinder Head Assembled is a precision-engineered small block Mopar head designed for builders and engine shops seeking maximum flow characteristics and combustion chamber optimization. This fully assembled cylinder head combines a 190 cubic centimeter intake manifold port with a power port design to deliver superior air velocity and charge distribution critical to high-performance engine builds. Pre-assembled configuration eliminates bench work and minimizes assembly turnaround time for shops running production schedules or individual builders working on deadline.

Key specifications reflect Trick Flow's commitment to flow efficiency and mechanical compatibility. The 60 cubic centimeter combustion chamber balances compression ratio with detonation margin across a wide RPM band. Valve configuration—2.020-inch intake and 1.570-inch exhaust—maximizes breathing while maintaining structural integrity under high-lift camshaft loads. The 1.560-inch spring diameter accommodates aggressive valve timing without coil bind, critical for applications running solid roller or hydraulic roller camshafts at elevated spring pressures. Straight-plug design ensures compatibility with standard ignition systems and simplifies head gasket sealing. Aluminum construction keeps rotating assembly mass low, reducing inertial losses and improving throttle response.

This assembly serves small block Mopar engine builds across street performance, bracket racing, and marine applications where intake port velocity and chamber design directly translate to peak horsepower and torque delivery. Builders upgrading from factory heads gain measurable flow improvements; machinists integrating this head into complete engine packages appreciate the pre-assembled condition and dimensional consistency. Weighing 31.15 pounds and measuring 9 by 7 by 22 inches, handling and installation fit standard small block engine stands and workbenches.

Trick Flow's aftermarket cylinder head line represents decades of port flow research and dyno validation specific to Mopar architecture. Small block Mopar platforms—whether LA or Magnum deck—benefit from modern port geometry that balances low-end torque with peak power output, outperforming factory casting designs in both naturally aspirated and forced-induction configurations.
