I just got a call from ESR stating that the 350 power valve cylinders have arrived that have been on back order. I am wondering...have any of you got or know of these "Polandas"? How do they run compared to the ESR? Durability?

Then I know there must be a bunch of people that port cylinders, who do you guys recommend, who do I stay away from? I am looking for a port job that will allow me to play in the dunes/ fast forest roads and drag race.
