2020-02-24 20:42 Everyone knows that 4V heads are for high rpm use. Designed for NASCAR, the ports on these heads were large, perhaps too large to be offered in heavy cars which never saw the high side of 5000rpm. The port on the left is a 4V intake port, while the right pic is a 2V. A 4V port measures 2. 47 x 1. 47 . A 2V port measures 2. 05 x 1. 37 . Now

Nov 19, 2002 whats the difference between 2V and 4V heads? howdy people, I cant remember if there was any difference with the combustion chamber or valves with the six cyl 2V motor. these are pretty rare, much rarer than the 4V V8 heads. so all this 2V and 4V is all ford stuff, so holdens don't have anything with 2V and 4V, so it is all Ford stuff? difference between 2v 4v heads ford Aug 27, 2014 Dyno 351C 2v vs 4v Heads.

The heads are so different that they require 4V2Vspecific intake, exhaust manifolds and associated gaskets. 4V 351C heads have enormous intake& exhaust ports that mate to radically different, 4V style intake and exhaust manifold flanges. The biggest physical difference between the 2V and 4V Cleveland heads is the huge intake and exhaust ports on the 4V heads. There simply isnt enough material around the smaller 2V ports to hog them out to mate to 4V port dimensions.

We are not affiliated with Ford Motor Ford made both 2V and 4V cylinder head versions for the 351C, with the latter 4V heads being the more performanceoriented versions. Unfortunately, Ford only produced the 351 Cleveland for five years (in the U. S. at least, Australia got the engine up until 1982). the 2v also came out with a 4 barrel carb as well. the term 3v is not a ford head but an after market head. it uses the 4v heads valves which are much larger than the 2v and uses the 2v ports which are much smaller than a 4v which gives better low to mid range torque.
