Hey Tommy sounds like u bounced right back.
My manifolds blew the gasket in the center bottom.
Find a Machine Shop and have the manifolds planed.
They are 45 yrs old and warp.
Use metal insulated gasket and buy a can of copper gasket sealer.
Broke the studs off with the long sleeve and had both manifolds planed.
Looking at your pic of possible leak the manifold bolts look nasty.
Take care of yourself have someone do the work.
