I sort of did the same thing. Mine project is still in the "Evaluation" phase. What I elected to do was to eliminate the heat spacer between the intake manifold and the carbs. I am using the stock TR3A carbs and air cleaners and still have 1/4 inch between the front air cleaner and the inner fender. I drove it a few hundred mile last summer like this and have noticed no problems due to removing the heat spacer. I don't have the intake manifold bolted to the exhaust manifold either because I don't drive it in cold weather and have no need to heat the intake.

Did the same thing, had to use the real narrow  1/2 inch? And cut the bottom
off the front one.
