SBF SHP Cylinder Head 175cc/62cc - Bare

The DART SBF SHP Cylinder Head 175cc/62cc Bare is a high-flow bare casting engineered for small-block Ford performance builds. This aluminum cylinder head features a 175-cubic-centimeter intake chamber and 62-cubic-centimeter combustion chamber, designed to maximize air scavenging and combustion efficiency on carbureted and naturally aspirated engines. The 2.020-inch intake and 1.600-inch exhaust valve configuration provides the port sizing necessary for aggressive cam profiles and elevated RPM operation while maintaining street-friendly characteristics.

As a bare casting, this head arrives unfinished and ready for machine shop preparation—valve seat cutting, port work, and final honing. The angled spark plug configuration suits both stock and custom intake manifold designs. The aluminum construction keeps rotating mass minimal, a critical factor when building engines targeting consistent performance across the RPM band. Buyers should plan for professional machine work to achieve proper valve timing, deck height matching, and combustion chamber volume optimization before installation.

This casting is suited for enthusiasts assembling small-block Ford performance engines—whether for street duty, weekend track sessions, or vintage engine restorations where modern flow characteristics enhance reliability and output. The 175cc intake chamber balances cylinder head flow with intake manifold compatibility, eliminating the mismatch problems common to oversized heads on stock manifolds. Buyers integrating this head into existing engine programs should verify port matching with their intake selection and confirm that existing gasket surfaces and bolt patterns align with their block revision.

DART's SHP line represents mid-range performance casting quality—suitable for builders seeking better flow than stock units without the premium cost of fully ported or CNC-machined heads. Proper machine shop preparation, including valve guide sizing and seat geometry, is essential to realizing the flow potential this casting provides.
