I have had some Pontiac bad luck lately . So here it goes . Today my goal was to install my Gardner exhaust on my 69 Grand Prix HO with the original long branch headers and ran into a little issue with one of manifolds…. See pic

What is the best way to remove that bolt without breaking the manifold? I’m pretty sure the bolts have never been removed. The exhaust looks original minus the mufflers.

Thanks

Once again the pics rotated
