What is the valve size on a 1967 Ford high performance head?
What is the valve size on a 1967 Ford high performance head?
Valve and port size is identical to 289-2V/4V heads. The 1967 289 High Performance head has slightly larger ports with the same valve size. The 221/260/289 combustion chamber looks like this, wrapped tightly around a pair modestly sized intake/exhaust valves.
When did Ford change cylinder heads and valvetrains?
Beginning May 2, 1966, Ford changed both cylinder heads and valvetrains on 289 engines. Prior to this date in production, Ford had pushrod guide holes machined into the castings. However, from May 2, 1966 on, Ford found a cheaper way to make 289 engines.
What are the casting numbers for a Ford cylinder head?
Casting numbers evolved to C5DE-B, C6DE-G, C6OE-M, C6DE-C, and C6DE-E. The C6DE-C and C6DE-E heads are Thermactor smog system castings and not of much use unless you are performing a restoration on a 1966 Ford or Mercury originally fitted with this emission-control system.
What kind of cylinder head does a Ford 390 have?
And because the Low-Riser head isn’t much different than the 390 High Performance or many of the standard heads, you have a huge playing field with which to work. FE cylinder-head identification begins with casting numbers; then, visible identification. This is a 1961 390 cylinder head—C1AE-A.
Valve and port size is identical to 289-2V/4V heads. The 1967 289 High Performance head has slightly larger ports with the same valve size. The 221/260/289 combustion chamber looks like this, wrapped tightly around a pair modestly sized intake/exhaust valves.
What kind of intake manifold does a Ford 2V use?
This design became the standard in the 2V engine through its production run. The first 4V heads used a dual-port intake manifold that consisted of a square port primary intake runner and a round secondary port for use above 3,000 rpm. These heads work adequately, but have some issues with low rpm torque.

What kind of manifold does a Ford 4.6 DOHC engine use?
Sullivan Performance has developed a high-rise single-plane manifold to fit the 4.6 and 5.4 DOHC engines. These manifolds are optimized for use between 2,500 and 7,500, and come with a standard Holley bolt pattern.
How are Ford cylinder heads and valvetrain interchange?
You can use the social sharing buttons to the left, or copy and paste the website link: https://www.diyford.com/ford-cylinder-heads-valvetrain-interchange-small-block/ The 221 cylinder head is identifiable at a glance by observing its small kidneyshaped 45- to 51-cc combustion chambers along with 1.59/1.39-inch intake/exhaust valves.
What kind of cylinder heads does Ford Racing use?
Ford Racing has a longstanding history with aftermarket parts. Specifically, their latest generation GT40 aluminum cylinder heads. Based off the original and incredibly popular GT40 iron head (from the 90s), Ford has continued to improve the design over the years.
