SBF 180cc Alum Cyl Head 58cc 1.94/1.55 Assembled

The SBF 180cc Aluminum Cylinder Head with 58cc chambers and 1.94/1.55 valve sizes is designed for Small Block Ford engine builders looking to enhance flow characteristics and combustion efficiency. This fully assembled FLOTEK head is ideal for applications ranging from street-strip builds to competition engines. It addresses factory flow restrictions that can limit mid-range power and peak horsepower potential.

Constructed from aluminum, this head features 180cc port volumes and 58cc combustion chamber geometry, which work together to improve mixture motion and burn rate. The 1.94-inch intake and 1.55-inch exhaust valves are optimized for flow-to-lift ratios across the RPM band, making it suitable for natural-aspiration tuning where every cubic centimeter of intake charge is crucial. The fully assembled design includes pre-installed springs, keepers, seats, and guides to factory specifications, ensuring bolt-on readiness for your engine build.

This cylinder head is particularly beneficial for builders upgrading older OEM heads or standardizing component quality across a fleet. It is compatible with various SBF platforms, including 289, 302, and 351W engines, making it a versatile choice for performance enthusiasts. The 58cc chamber volume provides reliable detonation margins while maximizing performance potential.
