How many of you PA,OH,MI, IA etc FFW

The one i had whoever rebuilt it before took a reamer to the top of a couple of cylinders...the new pistons will have the top ring hit this part and im not taking any chances. 2nd one was all gunked up with grease i got from a local guy....turns out to be rusted to the point of a .030 over bore wont fix it. Good thing he is gonna give me my money back. Third one is really clean...so im praying it checks out alright.
