Carb Insulating Gaskets, Where to get? Options

[HarveyH]

I'm getting ready to do a clean and kit on my 40IDF's this Spring and a question came up. I seem to remember talk about using insulating spacers for mounting. There doesn't appear to be anything like this on my current setup.
Do these go between the carb and the manifold or between the manifold and the cylinder head? (2.0L heads)

Who sells them? Part #?

Correct mounting gasket - insulator - gasket?

Currently a few threads exposed at the carb to manifold mount and the manifold to head mount. Will I need longer studs?


I've tried a few search criteria but didn't seem to get the right wording...

Thanks,
Harvey

Yeah, you want to use phenolic spacers to keep the head heat from moving up the throttle body into the carb. make sure that you polish the base of the manifolds with 400 grit sandpaper over glass. You will be amazed at how poorly they are cast, and those flaws will all be air leaks if you don't mill them down.

You will probably need longer studs. I did. I just made them from a length of m8 threaded rod. Real easy.
