All Small Six Keeping the carb cool

Aluminum is a good conductor and will also conduct heat to the other side, steel would better, and better if mirror finish on the side to reflect heat away. A barrier of anything would be better than none.
I agree with what Frank said.

A little off topic here but I fould a PEEK capable printer for relatively cheap. If i get it and it can actually print well then I could make all the adapters/spacers out of peek or pekk which would eliminate the need for phenolic spacers. Aluminum has a heat transfer of about around 205 W/m·K while PEEK and PEEK adjacent materials have about around 0.25-0.29 W/m·K. The pps-cf10 is around .5 because of the carbon fiber in it. But either way a plastic based adapter insulates way better than the metal ones. How long the plastic lasts would be the only potential issue.

Anyone in here know someone who has had experience with PEEK? Not very many people have access to it. Its mostly used by engineering companies.

You'd be better off machining blocks of PEEK.

You're looking at around $400 for 1.1 Lb of PEEK filament (half of a standard 1kg (2.2Lb) roll ~$20), one of the most EXPENSIVE printing materials that would take a 'not off the shelf' printer to even print it, heat enclosed print area and a print head that can get to the print temps of PEEK and not melt itself.

You then run into issues of proper layer to layer adhesion, and getting it printed 'air tight'.

I use a PLA plastic tube I printed up at 98% solid as an oil separation filter in my shop compressor.

Alternately, you could have PEEK printed up through a 3D print service, MUCH more simple and cost effective compared to trying to print PEEK at home.
