SBC 180cc Alum Cyl Head 64cc 2.02/1.60 S/P Bare

The FLOTEK SBC 180cc Aluminum Cylinder Head with 64cc Chamber is a bare cylinder head engineered for small block Chevy engine builds. This component delivers a straightforward, no-frills foundation for custom engine assembly, offering the core airflow and combustion chamber characteristics needed for both street and performance applications. The 180cc intake port volume and 64cc chamber size are the critical specifications that define this head's flow characteristics and compression ratio compatibility.

The 2.02-inch intake and 1.60-inch exhaust valve sizing reflects a balanced port design suitable for mid-range displacement engines. Aluminum construction provides thermal efficiency and weight savings compared to cast iron alternatives, while the straight plug configuration simplifies installation into compatible engine blocks. As a bare head, this component arrives unassembled—no valves, springs, rocker arms, or gaskets included—giving builders complete control over valve train selection and chamber prep for their specific performance targets.

This head is suited for engine builders and restoration specialists working on small block Chevy platforms where port volume and chamber size are critical factors in tuning. The 64cc chamber volume influences static compression ratio calculations—essential data for carbureted, EFI, and boost applications. Whether sourcing a replacement head for a complete engine rebuild or assembling a custom long-block, the FLOTEK SBC 180cc meets the foundational requirements of serious engine development. The 22-pound weight reflects aluminum's density and is typical for heads of this displacement class.
