Default Did compression test today

So, as a 1.5 year check up I changed the spark plugs and while they were out I did a compression test, numbers are as follows :-

#1 159
#2 145
#3 145
#4 140
#5 138
#6 140

As I don't really know the stock ranges can anyone give insight as to the health of my engine after 13k of 17.5psi

for a lower compression motor thats fairly normal IIRC. Stock motors are in the 180 range, low compression in the 140-150 range normally..
