Why do you want to go through at 7500? A few more cubes, a taller tire or less gear will allow less stress on the valvetrain.
When I run the numbers and use my combo as a way to figure power needed, I suspect you will need more power than the -1 heads can provide. Mine shows 841 up at 2000 d's to run 8.88 at 3065 lbs. The same calculated said 2200 lbs running 7.90 at 175 would need over 900 hp. IMHO if you run in air similar to me you would be needing about 1000 dyno hp to be sure to meet your goal. That would take better heads to easily make the goal with a reliable motor.
