Are 302 heads interchangeable?

Are 302 heads interchangeable?

Like the 289 heads mentioned earlier, all 302 heads are the same except for Thermactor provisions. There’s also a truck head (C9TE-C), which employs a 58.2-cc chamber for slightly higher compression. Ultimately all 302 heads were carryovers of the 289 head, making them all interchangeable.

Will a 302 intake fit a 351C?

If your 351 Windsor motor was a 1976 or ealier build, then the 302 intake would not fit. From 1977 onward, the 351W shared the same head casting as the 302, differing only in bolt hole diameters (7/16 inch for 302, 1/2 inch for 351W). Thanks for the clarification, correctness is in the details.

Will 351 Cleveland heads fit on a 289?

My understanding is that you can’t put a 351C intake on a 289, it’s too big. What you have to do is use a 289 manifold with the 351 heads. That’s why everyone uses 351W on a 289.

What kind of head does a 351 Cleveland cylinder head have?

351C-4V closed wedge chamber, boss/high-output head (adjustable rockers with screw-in studs) 351c-2v open chamber (bolt-fulcrum) 351C-4V open chamber (bolt-fulcrum) 351C Australian head (2v ports with closed wedge chamber) 302C Australian head (smaller, closed wedge chamber)

Where was the Boss 302 cylinder head cast?

Cleveland foundry castings have this CF logo. Though we call these engines “Clevelands,” cylinder heads were also cast at the Windsor, Ontario, foundry and have a “WF” mark. Here’s a “WF” (Windsor) casting on a Boss 302 head, which demonstrates not all Cleveland heads were cast at the Cleveland facility.

Is the Cleveland 302 block open or closed?

It is a closed-chamber Cleveland head casting with cooling passages for the Boss 302 block and induction. Note the milled pedestals and screw-in stud holes. Poor quench and chamber irregularities that cause spark knock make the two open-chamber heads unacceptable for a high-performance Cleveland.

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’s the difference between Boss 302 and 351C cylinder heads?

The 1969–1970 Boss 302 cylinder head is little more than a modified 351C head casting revised for use on a 302 block. The primary difference is cooling passages, because the 351C has a dryintake manifold and the Boss 302 has a wet one.

What kind of head does a 351 Cleveland have?

The 351C open-chamber head (2V and 4V) is a poor choice regardless of what you intend to do with your Cleveland. People associate this chamber with the smallport, 2-barrel head; however, it is also the 4-barrel head chamber for 1973–1974.

It is a closed-chamber Cleveland head casting with cooling passages for the Boss 302 block and induction. Note the milled pedestals and screw-in stud holes. Poor quench and chamber irregularities that cause spark knock make the two open-chamber heads unacceptable for a high-performance Cleveland.

What’s the casting number on a 302C cylinder head?

What you get with the Australian 302C head is smaller, 57- to 59-cc chambers and higher compression. Casting numbers begin with “AR” along with a North American number on the valley side of intake ports. For example, “ARD1AE” on one and “6090A” on the other stands for “AR-D1AE-6090-A.
