Was told whatever you use for spacers it should be the same as the intake manifold, so if you have one big hole in the intake manifold that’s the type you should use with spacers.

These aren’t phenolic but they did start life as 4-hole ported spacers until I opened them up. I still wanted to retain the split plenum feature of the dual plane intake so I left the divider intact. Eventually, I’ll do the same to a set of phenolic spacers to stop the heat soak that we all know these carbs are known for. It’s actually kinda hard to find phenolic spacers that have both carb bolt patterns like mine shown in the photos but Trans-Dapt makes them . . . expensive, but they make them. BTW, check out that gasket mismatch that needed some re-work! B61ACFB8-C49F-43F0-B644-36F067AD52FF.jpeg E0472A3E-33B8-4469-88CB-FE804A79BF60.jpeg

That's a great idea, never though of doing that. Looks like something else to do this winter.
