Default piston size?

my pistons have sp0.05 and 91.275 marked on them so does anybody know what the actual size is?

Is it just a technical way of saying .5 oversized lol

this might be a useful link for you, also if you look on ebay you can get a dodgy ford cosworth workshop knock-off CD for about £2, might be worth a punt for some of the tech info
