Piston Clearance Question

[Pappabob]

About 60 years ago, my brother purchased 2+ complete Model A motors all in pieces. His idea was to have "spare parts". Till now, that's all they ever amounted to while being stored under our dad's house and, later, at my brother's storage shed.
Recently, I learned my brother was looking to "make space" so I asked him to "donate" those two motors so I could attempt to assemble one, on a display stand, from all the best parts (some of us are a bit "strange" and actually "enjoy" work). I'm just getting started with this process. Have sorted parts and am working on some cleanup and parts sourcing (little Dearborn).

Finally, my question: Can someone tell me what the piston to cylinder clearance be on a Model A engine?? The motor I'm going to use is a 31 and appears to never have been rebuilt. It still has "Ford" pistons that appear to be standard bore. Babbitt looks thin (mains) but, otherwise good. Rods look really good!!

Thank you.
