congratulations! good find. I'll keep that in mind to always do good marking when removing vacuum lines.  I don't know about you, but I always sleep really well after I find/fix an oddball problem!

I finally found the source of the leak. It turns out it wasn't even an exhaust leak. The source of the sound was caused by the vacuum lines being switched at the top of the fuel pump. It made a phfft phfft sound that sounded a lot like an exhaust leak. Oddly it sounded like it was coming from the passenger side but that wasn't the case. I changed the the passenger side exhaust manifold gasket. I eliminated the heat riser thinking it was the source but it wasn't. I even put the original A intake manifold back with the teapot and that didn't help. I was really stumped. The sound only occurred while accelerating. I couldn't duplicate the sound while the car was standing still and revving the engine. The thought of switching the two vacuum lines around on the fuel pump came out of the blue. Sure enough that solved it. I would have never thought the pump lines could be switched and cause problems.
Finally the problem has been solved!

I think I found the leak. I took the intake off and saw some soot around this mushroom looking plug on the drivers side. I'm hoping this was the source of the leak.

I bought 2 teapots from him and thought his price VERY reasonable!! Contact him. I believe you will be pleasantly suprised. And yes, the quality is beyond reproach.

Yes I've heard of Sciala and that he has a good reputation and expertise. I don't need really need show quality, just quality. I hope I can afford his work.

Try this guy, if you're on the fordbarn.com forum you may know him. He rebuilds teapots and gets boffo box office from his customers.

I'm almost thinking about going back to the original manifold and carburetor. Who does good work on T-pots?

I had a chance to drive it today. Same issue after replacing the passenger side gasket. I'm beginning to think the intake manifold may be the issue because I don't recall hearing any exhaust leak with the original intake. Could the heat riser area of the intake leak enough to cause a sound? That's the only place I can see what appears like light signs of exhaust soot but it could just be heat discoloration too.

I did have the rocker off for the rear bolt and it was easier than the time I was tightening it. It made a difference. I also used a shorter box wrench although not a stubby so I used my favorite offset 9/16 to finish tightening it.
The exhaust pipe runs through a section of the frame so there's not enough room for the pipe to drop down enough with the studs in place. I'm hoping the passenger gasket was the problem.

If You take the Rocker Cover off that last Bolt is easy using a "Stubby" 9/16 Wrench. A regular 9/16 can be used for final tightening.. The Flange Gasket should be replaceable if You can undo the Nuts from Studs. If You have to undo the Muffler Hanger that should allow enough movement to pull Pipe down.Otherwise undo the Nuts and take the Exhaust Manifold off. Its about the same amount of Time I think.
