So I am wondering what would be the best runner to get tapped to install an EGT probe. I think I read somewhere that on the 5SFE runner number 4 tends to run lean due to the design, or something like that. If that is the case I would imagine that it would be the one that may have higher temperatures and therefore it should go in there.

Just wondering what your thoughts are for which would be the hotest and therefore optimal one to get tapped for an EGT probe.

Also, I have shown Manny's picture of his manifold and am hoping you can let me know which runners are what number. Manny, which runner did you tap (is that #2) and would you pick a different one if you were to do it again?

That's the number 3. I can't add anymore.

runner 3 is the place to be. just like manny did it.

#3, nice and close to the head.

whichever runs the leanest, so look for the whitest spark plug.
