Exhaust Manifold Removal

[1970 skylark 350]

I have found some other issues regarding the 350 in my 1970 Skylark. I noticed an exhaust leak around the passenger side exhaust manifold where the manifold bolts to the cylinder head.

Is there any tricks to removing this? It is 45-years-old and it looks like I will need to remove the starter and transmission lines in order to access all the bolts and get the manifold out and back in.

The manifolds are easy, soak the bolts in pb blaster and use a 14mm socket. I didn't have to remove the starter, it helped me to disconnect the motor mounts and lift the motor to access the rear bolts and the center bolt.
