Is he planning on lateral or vertical gas ports? You don't really need gas ports for what you are doing. The extra pressure from the gas pushing on the ring to keep it sealed will wear the rings and your bore quicker. If you just plan to race your car it will be fine, but if you plan on street driving it then I would tell him you don't want gas ports. You won't be making enough power to see any benefit from gas ports imo. Get a good set of rings with a steel top ring and you will be fine.
