What kind of water pressure are you seeing ?
If I can't achieve what I'd like with the crossover, then I may go that route. I want to further troubleshoot before going down that path though.
My pressure is at 2-3 psi at idle and it increases accordingly throughout the rpm range up to 24-25 psi at WOT.

Shhhhh. Recirc pumps take less than 10hp to turn just under 6000rpm. I think I saw 4hp loss at 5k. And that was V-Belt's, not serpentine which would be a tad less hp used. Shhhhhh.

You'll get some more help on this thread, which you have had good help already, but in meantime do a search of crossover's on this site and you'll see probably 20+ a year. It will give you a good handle on the -'s, +'s, set up differences, and what app's usually have better success using them.

Have temps been check with IR temp gun at the thermostat?

This is not my engine, but it's the same setup.
Bottom of crossover is fed from Power Steering Cooler.
Top of crossover feeds the T-housing and bypasses to my headers/risers.

Yes, I have used a IR gun to confirm temperatures.
Temp at the T-housing ranges between 98 to 105 degrees.
Temperature throughout the Intake Manifold is the same.
Temp throughout the entire crossover is around 98.
Temperature on my heads ranges between 114 to 125.
