Insulating I6 Exhaust Manifold Photos

[Sharps40]

For prevention of post shut down fuel bowl percolation/boil over.

Has anybody here insulated their stock 230/250/292 intake/exhaust log against the low boiling point of modern fuels? i.e. to prevent post shut down percolation due to heat soak.

If so, post up pics.

I am running a test on John Lee, got the front 2/3 of the logs insulated with muffler packing to see if it helps. Temps in the bowl shot up to 105+ with the warm days this weekend....pretty much saturatin the intake plenum and leaking out the butterfly shafts.

This morning's run shows nothing but condensation on the outside of the carb and adapter after a 38 mile run.

We'll see over the next few days but if ya got somethin done that looks decent and works....show me! Please.
