Speedmaster PCE281.2060 Ford 302/351C Cleveland 220cc Hydraulic Roller Assembled Cylinder Heads

The Speedmaster PCE281.2060 aluminum cylinder heads are engineered as a direct performance upgrade for Ford 302 and 351C Cleveland engines with both 2-barrel and 4-barrel configurations. These assembled cylinder heads feature gravity die-cast aluminum construction that significantly reduces weight compared to OEM iron castings while improving heat dissipation and allowing higher compression ratios before detonation occurs.

Key Specifications:

• 220cc intake port volume with redesigned raised floor intake ports
• 64cc combustion chamber volume
• Maximum valve lift: 0.580 inches
• Coil bind: 0.740 inches
• Hydraulic roller camshaft compatible
• Installed spring pressure: 145 lbs at 1.9 inches (intake and exhaust)
• Closed seat pressure: 145 lbs
• Open seat pressure: 360 lbs

Design Features:

• Re-engineered intake ports with raised floor design to optimize the massive cross-section found in OEM 4-barrel Cleveland heads
• Improved flow characteristics over stock castings for better performance
• Lightweight aluminum construction reduces overall engine weight
• Enhanced detonation resistance allows for higher compression ratios
• Fully assembled and ready to install

Important Gasket Requirements:

Due to the unique raised port design of these 3-valve style heads, specific intake gaskets are required. The intake gaskets measure 1.73 inches wide by 2.140 inches tall, with the port floor positioned 1.220 inches up from the deck surface. Speedmaster SM3282 intake gaskets are recommended. The exhaust ports use standard Cleveland 4-valve exhaust gaskets such as Speedmaster SM3274 or equivalent Fel-Pro gaskets.

These cylinder heads provide a cost-effective alternative to rebuilding original equipment castings, delivering superior flow, reduced weight, and improved performance right out of the box for Ford Cleveland engine builds.
