ya take the head to get looked over by a pro he will tell you if he finds a problem, with as much oil as you had leaking by if there is a problem it will be very obvious. couldn't tell by the pic... can you still see the original honning marks??? if you can still see them and they don't look worn all wierd... its a bit easier than pullin out your calipers. as for #2 cyl. take it out and inspect the rings, you should [ay real close attetnion to the oil control ring, if it's all pluged up or don't look right, replace it.
