Insulating Against Heat on the Carb

Obviously there has been a good deal of discussion on FABO about Edelbrock carbs and heat soak or fuel boiling issues. I am committed to keeping my Eddy carb, so I figured I would pose a question that surprisingly does not have a solid answer here on the forums. Given the following three options to best reduce heat soak or boiling fuel, which of the three would you choose:

1. Phenolic spacer (1/2" due to underhood clearance issues).
2. Wooden spacer (1/2" for same reason)
3. Edelbrock heat insulator gasket (I believe this is about 0.3")

The carb is mounted on a Mopar intake that looks very much like the Edelbrock Performer intake. I have read through a number of the threads that also addresses steps like adjusting floats and such. Those things will probably be addressed in tuning. But the carb will be mounted on one of the three options above, so I was curious what people thought would be the best option? Thanks as always.
