Fell for a dumb video saying how easy these were to convert. Bought a conversion kit and of course, it works…but only at super high temp even on low. It’s a nice grill and I’m too invested to turn back now. Do I need a replacement entire manifold? Or, can I get away with just swapping out the 3 burner valve controls. My grill is a 2015 SPIRIT S-315 NG SS US/CA.

A replacement manifold would be ideal unless you can source the proper valves. You may also need a regulator and hose as well as a tank scale/holder.
I replaced the hose, regulator and orifices. Here’s what I was thinking about buying instead of the manifold. They say NG or LP
Here’s the conversion kit I bought and installed

I don't see how those will work any better than what you've done. The valves themselves are very different between NG and LP. I think you should find the proper LP manifold for that grill.

Yes, the spools in the valves are different as well as the orifices.
