Default Boss 9 heads

Just picked up a set. Have been running p51s in my car. It has been running 9.0s @149 3450 with me in it. We have to see how the boss 9 heads do.

How much of a difference is there between the 2 when it comes to power gains? NA and will be nitrous based. The motor will be a Daily driver with a kick in the ***.
