Ford Heads

CLEV 2V CAST IRON COMPETITION PORTED CYLINDER HEADS -192CC

FORD 2V CLEVELAND CNC PORTED / ASSEMBLED CYLINDER HEADS

 

 

 

RECOMMENDED USE AND INFO:

Suitable for 351 to 408 cubes Cleveland Stroker Engines.

These CNC ported Ford 2V Cast Iron Cleveland cylinder heads produce 505HP normally aspirated at 7000 Rpm with our custom Pavtek solid camshaft and a TFC single plane intake manifold. They also produce an impressive 481 HP @ 6800 Rpm with an Edelbrock Rpm Airgap dual plane intake. These cylinder heads are for the Ford enthusiast  that wants to retain the authentic OEM look and would prefer not to use aftermarket heads. The OEM cylinder head has many flaws in it's original design and we have spent countless hours re-developing these ports to achieve the maximum power potential within the restrictions of the factory castings.

We have also modified the shape of the OEM 2V close chamber cylinder heads to enable them to be used on 351 and larger cubic inch engines. Combustion chamber volumes are available between 62 to 72cc depending on how much the heads are final milled.  The cost of machining the cylinder heads to suit screw in studs is also included in the price of the CNC porting.

On a 383 c.i Cleveland with a mechanical Street Roller camshaft these heads had enough flow to produce 480 Ftlbs @5250 and 547 HP @ 6500 Rpm all with just 10.5:1 Compression.
