Len, It looks like you do have .060 over pistons and the block is also bored .060 over. If you just leave the cylinders alone and don't hone them you will end up with roughly .003 clearance. For a street motor that will not see any hard times, that's fine. But, if you are going to run this harder than normal, the clearance is a tad too tight. For the bore you have, you should have .005 clearance. You can get it by honing the block. If you're gonna order a set of pistons, then obviously you want .060 over.Mike Casella
