4V Ford Cleveland

Finally a true factory style 4V alloy head for the Cleveland enthusiasts. At CHI we realise that not everyone wants to upgrade their intake manifolds, so we went about creating a 4V head for the Cleveland enthusiasts. Designed around our 3V 218cc intake port we spent many hours re shaping the entry of the 218cc port to accommodate factory and aftermarket 4V manifolds like the Torker, Strip Dominator etc etc. Careful attention was paid during development of the opening of the port, so as to not increase the volume of the port any more than necessary and keep the velocity as high as possible. Essentially we have created a full size 4V head with a port volume smaller than most “small port” epoxied 4V heads! The new head features the same standard height “UNI” exhaust port as our 2V head allowing the use of either 2V or 4V headers. The intake opening is as per the original factory 4V heads and will accept all factory manifolds. The 4V heads come machined to accept 2.190”Intake valves and 1.650” Exhaust valves and can be machined to accept 1.710”on request and at no extra charge.

With 325cfm of intake airflow and easy compatibility with existing parts the all new 4V head makes for the most economical horsepower and torque upgrade available for the trusty 4V headed. At just 228cc in port volume the all new 4V flows a massive 325cfm at .700”lift, taking the 4V head to a new level of performance, never before available from a standard intake port location and size.
