Message Stock is:

Top Ring: 0.0083"-0.0157"
Second Ring: 0.0197"-0.0299"
Oil Rings: 0.0079"-0.0299"

So if you plan on running a little hotter setup (which it seems you do) you can go maybe 25% larger on the gap for the top ring, near the top end of the range on second ring.

I would personally still keep the oil ring in the middle.

So tell him something like:

Top: 0.012"-0.020"
Second: 0.025"-0.029"
Oil: 0.010"-0.020"
