These CNC ported Ford OEM 2V Cast Iron Cleveland cylinder heads produce 505HP normally aspirated at 7000 Rpm with a street/stip solid flat tappet camshaft and a TFC single plane intake manifold. They also produce an impressive 481 HP @ 6800 Rpm with an Edelbrock/DRP 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 cylinder heads. The OEM 2V cylinder head has many flaws in it's original design and PAVTEK have spent countless hours re-developing these ports to achieve the maximum power potential within the restrictions of the factory castings.

The shape of the OEM 2V close chamber cylinder heads have been modified and CNC finished 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.
