Are the bolts harder than a Leaf Spring?
I have cut (actually very easily) leaf spring with a good
expensive hack saw blade, not the two dollers for five,
but prolly up to 3-4 bucks apiece kind.
Its surprising how easy it'll cut.
Are these harder than "grade 8"? 

O.K., no one has said it yet, so I will: CUTTING TORCH! You can borrow mine, and my fire extinguishers.

Is it portable?  I don't want to drive the car for fear of poking holes through the headers.  I KNOW the correct way to do this is to remove the UCA, but I am sick of working on springs.  I lost count of how many I have had on this car. Not to mention going through the loosening, retightening of the nuts that are very difficult to get a wrench on and turn.
 

  one  benefit of the coil over system...   

 

I bought some really long sawzall blades.  Later, I will see how much carnage I can create.  After mastercrap, what's a little more?

Those bolts are now history.  I went and bought some really long sawzall blades, then took the plate off the front of the sawzall so I could get it in there.  Those long blades wipped around and was getting nowhere.  In my sawzall blade collection, I had a few of those torch blades, 6" long.  Turns out there was room to get them in there by removing the plug wires and holding on for dear life while I went through 5 blades.  But it did the job !!!!

Only bad part was a broken spark plug, I think that got cracked when pulling the boot off to get the wires out of the way.  Touched up some scratched up shock tower paint.  Gotta love that rattle can paint that matches perfectly.

Thanks for all the ideas. 

Now, on to the muffler conversion (version 4.1).  I bought two mufflers from  Walker's aftermarket stuff.  These are 2-1/2 in and 2-1/2" out and configured like a Mustang muffler but about 3" longer. Looks like I can make them fit.  They are called QUIET FLOW, so I am hoping for some good results.  The application is a 79 Cadillac Eldo with 500 cubic inch engine.  It make choke the 427 down a few ponies, but that is a small price to pay to have a (relatively) quiet car.  I am betting it will sound pretty good...

Loud mufflers are just annoying if you want to enjoy the car.

It's a little too late at this point, but I would have tried the torch to heat the headers then drive something between the header and the end of the bolt to create the clearance. With my luck, I will need those threads back later.
Good luck with the mufflers. There is nothing better than the sound of a finely tuned engine, but I still want to hear the radio.
