Removing exhaust from manifold

Just ordered and received a new TTI exhaust from stock manifolds back. Any tips on removing the exhaust from the manifold. One bolt is real hard to get a socket on from under the car due to the bend in the exhaust. I’m thinking It would be much simpler to remove the manifolds. Also the spark plug heat shield prevents me from getting a wrench or socket on the top side of the bolt. It’s a 426 stock manifold.
