I agree with dfree383. Removing the hump helps and it looks good to open the ports at the gasket but leave it alone there. Smoothing it below the bowls helps. Look at some of the home porting info to get an idea. The idea of a junk head may also help you decide if you want to do it. I ported some E7's and could feel the difference and it was fun at the time and I learned a few things. One problem with the heads you have is huge combustion chambers. You should find E7's for $50 or less from the 5.0 guys and the smaller chamber and better flow will be worth it. I used both on the same engine so that would be my opinion.
