Why wouldn't you have the SN# ? The shops usually place stickers inside the engine compartment of the service dates.

yes that would work however my motor blew up and i got a engine from a wrecker which is why i'm trying to find out if it has been done or not. I don't have the serial number from the sled that it came out of

Look at where the spark plugs meet the head. If the spark plugs sit flat on the head then no update has been done. If the plugs sit in an indent, then the update has been done.

The plugs should be sitting in an indent (where the plug gasket meets the cyl head - almost like a cup) if the update has been done. If it has not been done then the plug gasket will mate with a flat spot on the head - no indent. If you post a picture of the plug i can tell you for sure.
