CHI release worlds only true Alloy 4V factory style Cleveland Cylinder Heads

21/11/2005

CHI is proud to announce the world's only true 4V factory style cylinder head. Our customers have been calling for a 4V cylinder head to take all factory style large port 4V manifolds, so we set about redesigning our 3V 218cc intake port to accommodate true 4V size intake manifolds.

By carefully blending out the entrance of the intake port we managed to create a full sized 4V intake port with a runner volume of just 228cc"s whilst retaining the all the good attributes of our world renowned 3V heads.

This cylinder head will accept all factory style 4V manifolds such as the Weiand Xcellerator, Holley Strip Dominator, Performer etc. Coupled with our standard height "UNI" ex port, these heads will accept all factory style exhaust manifolds, making them the ideal replacement for the famous factory 4V iron cylinder head.

Combined with our 3V combustion chamber these heads are the ultimate bolt on horsepower deal for those customers wishing to retain all their existing 4V manifolding.
