[Healeys] Phenolic spacers

To clarify, the kit came with four phenolic blocks or spacers.

Two are square with scalloped sides and four holes and mount between  the
carbs and the intake manifold face.

Two more are diamond shaped with two holes each to accept bolts to mount
either air cleaners or a CAB.

I assume they would provide some insulating value to minimize heat transfer
from the carb body to the filter or CAB but I really cannot see that this
would have any effect on the temperature of inlet air.
