As usual, some great advice, suggestions and direction. Thank you everyone for taking the time and effort to share. I re-read all these threads several times and I made a decision. I broke it down in 2 parts. The first part was the rocker nut clearance with the valve cover. I could accomplish this one of 2 ways; either cut the rocker nuts, perhaps all 16 of them, or get the thicker 3/8 inch gasket. Cutting the rocker nuts lost it appeal to me, so I elected to purchase the thicker gasket. I think that problem has been solved. Now, my factory choke. I know I'm stubborn on this because I really wanted to keep it, but this morning along with the thicker gasket, I also ordered the electric replacement choke. Got the gasket and choke from ShowCars. From reading the last few threads, there is a possibility that with a thicker carburetor gasket or gaskets, I still might be able to salvage the factory setup. I think it's best to get the valve covers on and deal with that issue first. Then I can see how the choke is going to line up and what might be done with it. If nothing, then I have the electric one ready to go. I don't suspect the parts will be in until the end of the week. Will keep you posted. Many thanks to all, Carmine.
