what size carb for a 416 stroker

Sounds like your current carburetor just needs to be tuned. A different power valve isn't going to do anything for the idle circuit.

Ya, I bought a vacuum gauge. I just need to learn how to proceed from start to finish to adjust/tune the carb. That is where I wanted to go, but I find sound bites and not a good start to finish approach?
