68 cuda 383 exhaust manifold removal

I can not give advice on the headers, but I had a coolant leak on one if the middle studs on re-assembly and was unable to remove the manifold with the column in. I was able to move it far enough back to get the stud out and resealed with theflon and reinstalled. It is not hard to pull the column back but I got lazy and just had got the car back together!
