Im still playing around with this and figuring out whats normal and whats not. Today when testing my car the intake temps were about 135 degrees and engine temps kinda jumped around.
After a coolant flush and replacement with 75% distilled water, waterwetter, and 25% coolant, I saw my temps were down to about 195, 197 but spiked a bit to 206. Could be just that the system needs to even out still.

My intake manifold gets hot to the touch and im considering a thermal gasket. With a cold air intake youd think id have lower intake temps.

Do any of you guys know your normal operating temps?
