The new and old castings are basicly copies of the a Honda 85 to 86 cylinder, the intake being almost identical. The bridged intake on the Honda cylinders came in 87 to 89 models.,..and yes these are IMO the better cylinders with the better intake design, much more support for the piston and rings.

The CP Industries Sphynx, Puma and Saber employ the bridged intake providing much needed piston and ring support. Unfortunately, the ESR & ProX cylinders do not.
