the idea is only to reduce temps.
they do this by insulating the mating surfaces, it has nothing to do with manifold design.

just pretend theyre the same as hondata gaskets which im sure you know what those are for.

 

HMMMM--i like easy power bolt ons. Getting more interested. Seems to be pretty convincing information.

I understand the concept about the spacers--GM tried to do this to their carbs in the late 70's/80's. I dont have any data on their results though. Most people would pull them and go with Holly or Carter AFB.

 

Well I have a stock lower, middle, and upper. Along with a dyno. I can send these out and do the testing. If someone wants to foot the bill I'm in.

 

This is an old thread, but did anybody ever make one of these? I could use one badly. My custom intake manifold is getting very, very hot.
