Question about motor mounts going bad

I was in the middle of my longtube header install and realized that I can't get the header to line up with the holes in the head.

One reason is that the flange is hitting the floor, the other reason is that the header is rubbing up on the AC line. I've been told that the BBK headers should clear everything fine time and time again, so I'm thinking that after 110,000 miles, the motor mounts are bad.

Is this an accurate assumption that the mounts have gone bad and the engine sitting too low is the problem?

I don't know a good or bad one by looking at them so I have no idea if they are bad or not. I'm guessing here, so any advice is gladly taken.

Thanks!

No pic, but I looked real good and long at the engine while trying to figure this out and the motor definitely leans to the passenger side a good amount. I've already ordered them since several other people on another board said they had the same problem, installed the mounts and everything fit fine.

Thanks for the reply!
