Speedmaster PCE281.2044 Aluminum Cylinder Heads Ford Small Block 289 302 351 Windsor 175cc 62cc

The Speedmaster PCE281.2044 aluminum cylinder heads are engineered for Ford Small Block 289, 302, and 351 Windsor engines, providing a high-performance upgrade from heavy cast iron factory heads. These assembled cylinder heads feature 175cc intake runners and 62cc combustion chambers, designed to support engine builds in the 400-700 horsepower range.

Key Specifications:

• Intake runner volume: 175cc
• Combustion chamber volume: 62cc
• Maximum valve lift: .580"
• Coil bind: .740"
• Valve configuration: Solid flat tappet design
• Intake valve spring install pressure: 130 lbs @ 1.8"
• Exhaust valve spring install pressure: 130 lbs @ 1.8"
• Closed seat pressure: 125 lbs
• Open seat pressure: 320 lbs

Construction and Design:

• Gravity die-cast aluminum construction for superior strength and weight reduction
• Uniform casting process ensures consistent port geometry
• Optimized port cross-sections increase air velocity for improved throttle response
• Fully assembled and ready to install

These cylinder heads utilize a precision gravity die-cast manufacturing process that creates a more robust and uniform structure compared to traditional sand casting methods. The aluminum construction significantly reduces engine weight while improving heat dissipation. The carefully engineered 175cc intake ports provide excellent airflow characteristics for street/strip applications, delivering gains in horsepower, torque, and fuel economy over stock cylinder heads.

Ideal for enthusiasts building performance-oriented Small Block Ford engines for street use, bracket racing, or weekend track duty. The valve train components are pre-assembled with proper spring pressures, simplifying installation and ensuring reliable performance.
