Looking at making up some of these. These are intended to help insulate the carbs from the engine further at the carb base. Who's interested?
These were available at one time for $15 each. I should be able to do a set of 4 for $24, if i can get some quantity. Figured I'd see how much interest is out there. Attached image(s) |

Just curious.
I have used just the head-->>manifold phenolic spacer and I have never had any heat issues on the manifolds or carbs. Sure, there is some heat from the studs, but never enough to make a big difference. Also, with these added gaskets, you are moving the throttle plate further away from the valve which does have a negative result. So, why add these? Rich |

Bruce I believe the benefit is the phenolic spacers stop the heat from traveling up the manifold. |
