Slant heat riser block off/delete?

I have a perfectly good manifold that I removed the heat riser from. It was a pain in the *** when I was living in the Seattle area. For about 9 months of the year, the weather is cool damp air under 50*. Carburetor icing is the result. Now that I live in the Columbia Basin area, I would not use it either. They have an actual winter here, last week the temperature was -5*. And I am sure that the carburetor icing would have been just as bad.

If the heat riser was not needed, the factory would have removed it. Removing the heat riser would have risen their profit margin. And the automobile manufactures are all about the profit margin.

Most people are still operating under Hot Rod circa. 1970 crap. Remember they were the ones that first published that flipping the pistons would gain 10hp in your Chevy 283. I think they made the same claim for removing the heat from the intake. On a V8 they are right, on an inline they are not.

And ever since, it has been an article of faith that you need to remove heat from the intake.
