Here are some pictures of a 351 Cleveland 4V head.  Notice the huge intake and exhaust ports size.

4V Intake Ports Huge!!!

4V Exhaust Ports - If These Were Designed Better, Power Would Increase Tremendously.

Also, the Cleveland heads came with open and closed combustion chambers.  The 70-71 4V heads had a quench chamber of 61.3 - 64.3 cc's and the Boss 351 heads had a quench chamber of 64.6 - 67.6 cc's.  On the other hand, the Cobra Jet, High Output or H.O., and the 2V heads all had open combustion chambers.  The CJ and H.O. heads measured in at 73.9 - 76.9 cc's while the small port 2V heads had a 76.9 - 79.9 cc chamber volume.

4V Closed Chamber Head

As you may be able to see, this particular head is machined for pedistal rocker arms.  351 Cleveland heads came with an adjustable and non-Adjustable valve train.  The engines that had the adjustable valve train were the Boss and the H.O. w/ the mechanical cam.  The engines without adjustability are the 2V, 4V, CJ, and the H.O. w/ the hydraulic cam.

4V Head Machined For Pedistal Mount Rockers. Notice The Rocker Mounting Surfaces.

Anyone with a 351 Cleveland that has a non-adjustable valve train can now easily convert to an adjustable one without expensive and non-reversable machining thanks to Crane cams.  They now offer a kit that comes with special guide plates and screw in studs that allows full adjustment of the valve train.  Just about anyone can Install this kit its so easy!!!
