What Spark Plugs Should I buy???

1990 560 SEC Euro Version
This may seem like a stupid question, but is there a difference in the recommended spark plugs for Euro version 560SEC as compared to the North
American version?
The reason I am wondering is that there is a significant difference in the compression ratios for these engines! Probably means different heads, so are the plugs different?
Follow up to the question above, does anyone know what the reccomended spark plug is for this car?
