Speedmaster PCE281.1724 CNC Aluminum Bare Cylinder Head Ford 302/351C Cleveland 235cc 71cc

The Speedmaster PCE281.1724 is a high-performance CNC-machined aluminum bare cylinder head designed specifically for Ford Small Block 302 and 351C Cleveland engines. This bare head is sold individually and allows you to customize the build with your choice of valves, springs, and valvetrain components.

Key Specifications:

• 71cc combustion chamber volume for optimal compression ratios
• 235cc intake runner volume for improved airflow
• 2.190-inch intake valve compatibility
• 1.710-inch exhaust valve compatibility
• Full CNC-machined ports and chambers for precision performance
• Gravity die-cast aluminum construction for significant weight reduction
• Redesigned 3V intake ports with raised floor to optimize port velocity
• Standard 3V intake port location with 4V compatibility
• Raised exhaust port configuration

Performance Benefits:

• Superior airflow compared to OEM cast iron heads
• Lighter weight aluminum construction reduces overall engine mass
• Allows higher compression ratios before detonation onset
• Enhanced port design addresses the massive cross-section issues found in factory 4-barrel heads
• Perfect upgrade for both 2-barrel and 4-barrel Cleveland applications

Installation Notes:

This cylinder head requires specific head gaskets for proper sealing with 351C blocks. Compatible gaskets include Speedmaster PCE348.1005 (MLS with 4.055-inch gasket bore) or Fel-Pro 1013 (Composite with 4.100-inch gasket bore), both featuring .040-inch compressed thickness. The unique raised port design requires Speedmaster SM3282 intake gaskets. Standard 4V exhaust gaskets such as Speedmaster SM3274 or Fel-Pro 1416 are recommended for exhaust sealing.

This bare head provides an excellent foundation for custom engine builds, offering superior flow characteristics and detonation resistance compared to rebuilding factory castings. Ideal for performance street applications, drag racing, and hot rod builds seeking maximum power potential from Ford Cleveland platform engines.
