You shouldn't need one to remove the piston. If you really really REALLY need one to remove a piston I'd imagine that block is warped far beyond the point of no return.

The piton is ~2.95 inches or 75mm so select your reamer on that.

24TEN - running a reamer around the top of a cylinder to remove carbon deposits is a common procedure in engine tear down. It doesn't mean a cylinder is warped.

If that's true then I learned something new. I've done 5-6 engines and never had to use that tool ever.

It was really common on the v-8's of year long gone. With quality fuel and periodic de-carbing I could see the pistons coming straight out. Of course you could also take the piston out the bottom.
