Ok good news the bolts tie the exhaust pipe the manifold haveet their demise (manical laugh).

I cut one of and bought broke me back loosening the other with brute force.

I am going to a machine shop with it to get the broke bolts out.

Next question replacement bolts? Stainless graded or what?

Congratulations! I hear that stainless bolts have issues seizing up but personally can't confirm that. I usually go back with Grade 8 bolts with high temp anti-seize. Once you have repaired everything you shouldn't have to split the two manifolds again, just remove them as an assembly.
 
I want to say thank you everyone that helped with this issue. I got the exhaust machined to remove the broken bolts. He also leveled the mating service between intake and exhaust and adjusted the heat riser. I got everything back together and properly torqued down.

When I got in to start her up she came right on and interestingly enough the tachometer was 300 rpm's above where it had been previously. I thought that was a bit weird and then it occurred to me the minor exhaust leak was also an intake leak. I adjusted the rpm's back down and took her for a spin. Totally different. The car has ZERO hesitation, quiet as a church mouse and SOO much more power.

So I guess all the work I have done to try and get it to run more comfortably totally made the difference once the leaks were fixed.
