Search the inline six forum for "intake manifold heat".

This was posted in your other thread you put up in the 80 to 86 forum (as well as my responses to your question about the heat plate).

Use the search function.

Click the image to open in full size.

This is what the manifold heating plate looks like. You cut one of your heating core lines and hook one end to each of the hose fittings, bolt the thing to the bottom of the Offenhauser 'C' or 'DP' with a gasket, and it keeps your Air/fuel mix nice and toasty.

*I notice that the old Clifford intakes had a hollow spot underneath them like the Offenhauser does for this purpose, but the Cliffy uses 4 bolts, and, I believe, the Cliffy holes are blind, and don't go all the way through.

Where does a guy get one of those manifold heat plates? I don't have one but I might as well try it since I've been having all of these same issues too. I need to read into recurving my distributor as well. With my 300 (see signature) the vacuum advance sends the timing all over the place and it won't run very good at all. Leaves me pretty disappointed for the amount of time and money I've put into it, really. I've tried setting the static timing from dead 0 all the way to 16*, same result every time, regardless of if it is plugged into the advance port or manifold vacuum. I've also tried setting the timing with a vacuum gauge as well as my digital gun. The advance sends it sky high and the motor bogs/misfires/pre-ignites. Would the flat tops I put in it mess with the compression ratio in such a way that it makes it this hard to time it?

If you buy a Fel-Pro intake/exhaust gasket set they include the gasket that goes between the manifolds - it is a perfect template for the heat plate.
