[T2] Rust, Noise, Heat

[Bob Pratt]

Has anyone attempted to try the changes found at http://www.type2.com/library/heat/Engine.html?
Now that Myles is back on the road and the New England weather is changing, I am looking into doing something about the noise and lack of heat.
Does anyone on the list have any thoughts about using Great Stuff spray insulation?
Again, thanks for any insight.

Bob
