Thanks guys, the one for 52 bucks is what I may do. I have a std and a .020. One other option is a block on ebay for 99 cents I can still see hone marks but the guy could have run a hone thru it. Shipping is 31 bucks so either I gamble with 32 bucks or just buy the 10 over piston. You cant really knurl a chrome plated piston as the hard chrome will crack off. Otherwise that would have been a option.
