I agree,

There is about .004-.005 taper in the bores which is not bad for these old engines.

If the bearings look good, hone the cylinders and lap the valves if that is all they will need or grind the valves and seats if necessary. This engine will run just fine for many more miles. be sure to change the timing gear if it is a fiber gear and look at the cam.

If you want the engine to be absolutely like new, then re-bore the cylinders, new pistons, valves cam and bearings etc. but for how most of use our Model A's. I think it will work just fine to work with what you have.

My opinion,
