Howls of Loneliness
No. You have 6 ev's spare after you have given your pokemon the max number of ev's it can have in one stat, which is 252. If you give your pokemon 6 hp increasing ev's (which audino gives though I can't remember offhand what amount of ev it gives) then your pokemon will have increased HP by 1 point aswell as all the other stats you wanted.
If you weren't aiming for maxing out 2 of your stats then this might be different, but if you are you are fine.
ok thank-you very much.so my horsea is fine.
