Last note and then I am going to bed. I am really leaning towards yanking the heads and trying the Eddys. I will need to buy new headers to use them anyway, so putting them on this car vs another seems like the best option for now.
Once I get the car back to where I feel safe and stable with it, this is likely the course of action I will take to try to get it down to 7.0.

I still want to hear opinions, and I will post and keep everyone up to date on the results.

Thanks to all.
