spring choice

ok so i bought a set of alum heads.
i was told my old springs were mopar performance set to match my
509* lift cam but there actually stock apparently and never got upgraded....
So will the 440 source springs be ok for this cam?...
I know that the advertised limit for these springs that come with the heads is 600 lift but is actually more along the lines of 550-560.
Im just not that familiar with cam/spring options and how important it is the be rite on and not under or over your lift.
