You are at the maximum for a gas engine so still good to go, T's like the extra .001" on nearly every thing compared to modern specs.

I with Frank. With a low speed engine like the T you will be okay.

Lorenzo, are you talking piston ring end gap or side clearance as you pic shows. At first I was thinking you wanted end gap which is measured by putting the ring 1/3 to midway down a bore, squared up with a upside down piston, and measure the gap between the two ends (general rule of thumb is .003"-.005" per inch of bore).

But your pic shows the side clearance, which is measured as shown. Both are important measurements that should be taken, more so end gap in my opinion.
