Intake Manifold Dilema

I'm looking for advice on what I need to do about my intake manifold dilema. I removed all of the port plugs and the fittings from my aluminum intake manifold (Eddy Torker II), and the threads for the heater hose fitting came out with the fitting (Yay). It appears that who ever installed it before me felt it important to cross thread the fitting. I tried to clean up the threads, but it's looking like a lost cause.

Here is my dilema, do I attempt to repair the threads in the coolant port, or do I update my intake to a newer design? If I do repair the threads, what is the best way to do so (Heli-coil, Permatex Thread Repair)?

And finally the subjective question, has anyone run the Weiand ACELerator, thoughts? I have also thought about an M-1 single plane, but that's getting a bit pricey.

I'll wait patiently for your advice.
