Will a 4V intake on 2V heads?
Will a 4V intake on 2V heads?
The short answer is yes, it will work, but it will also be a real pain to get sealed. The better answer is to pick up a cheap used intake on ehay that is made for a 4V head.
How do you tell a 2V head from a 4V form?
If the heads are off the car have a look at the exhaust port. If the port opening has an indentation where it passes around the exhaust bolt thread it is in fact a 4v head. If the port opening is nice and condistent all the way around it is in fact a 2v head.
How much horsepower does a 351 Cleveland 4 have?
Horsepower. The 351 was available as a two-barrel which was a basic engine and a four-barrel, or performance, engine. The two-barrel was rated at 240 horsepower while the four-barrel was rated at 285 horsepower.
Will a 351c 4v intake manifold fit on a 2V motor?
It’ll work, but that’s about it. A 2V Perfomer would work better and can be had used for under $100. I’d use the 2V gaskets because there’s more sealing area and the port mismatch is so huge that it really doesn;t matter.
What’s the difference between a 351 Cleveland 2V and 4V?
There are differences in the 2V and 4V, but you can bolt either on to the 351 Cleveland blocks as I have done this myself. I believe that was your question. You do need the matching exhaust manifolds, intake (some intakes work on both heads), and a 2V or 4V carb.
When to build a 351C 4V for the street?
Thus when building a 351C 4V for the street it is essential to use camshafts with conservative amounts of overlap too (50° to 62° based on advertised duration).
What’s the difference between a 2V and 4V Cleveland?
With the 4V Cleveland the duration of the intake event must be relatively conservative (270° to 290° advertised duration) to avoid softening the low rpm power by shifting the power band too high in the rpm range. A second difference of the 4V head is the size of the valves; the 2.19″ intake valve is 55% the size of the bore!

What’s the difference between a 2V and a 4V Cleveland?
The biggest physical difference between the 2V and 4V Cleveland heads is the huge intake and exhaust ports on the 4V heads. There simply isn’t enough material around the smaller 2V ports to hog them out to mate to 4V port dimensions.
Can a 2V head be machined to a 4V head?
Can the 2V head be machined to 4V specs, and can a 2V engine block be drilled for use with a 4V intake? A: Starting with the basics, 2V heads are designed for use with a factory 2-barrel carburetor option (2V = 2 venturi), while 4V heads came on one of the five Ford 351C engine configurations that came with a 4-barrel carburetor (4V = 4 venturi).
