Stazi,
How did you come by the measurements for you pistons? Did you measure the bore of that particular block you have or did you base them off of the stock listed dimensions for OEM pistons? What I'm getting at is do you know for a fact that your piston to bore clearance is .0045"? If not, then you're fooling yourself thinking he only has to clean up the block (that's strictly a best case scenario).
