Well my are already purcashed, and they do NOT ave gas ports.
Here's the deal, my machinist doesnt have a hone/torque plate for a large bore Hemi. This guy does A1 work, and he is considered a good friend also. I was thinking, that have a so-so hone job, that the gas ports would make up the diff and maybe then some.
He explains to me that the Hemi although benefits from a Torque plate, he is confident in making good ring seal without. He said some engine really need them like small block Fords etc.

OK
How much does it cost to have a set of piston machined for lateral gas ports?
I figure $150 range...but I dont know.
