Hypereutectic pistons are tighter around .0005 per inch diameter. You are just outside the cast piston limits. It would probably be ok but may be noisy. You can get .003 over oem pistons, might be an option. Or maybe go .010 over rings on the stock piston, file end gap for correct gap. Did you put the balance gears back in when you built it the last time? Yes, they still seem fine, but im going to get more intimate with it Share this post Link to post Share on other sites
