Need cam guru thoughts/advice

NC Engine Builder said

I'm no cam guru, but all you have done for the most part is remove lift, that seems like the wrong thing to do. Your @.050 numbers are pretty close to the same, so doubt the powerband will move much if any. And why would you have had the bullet in at 4 degrees retard?

I didn't build this engine, it was what was in the car when I bought it. I asked the previous owner why the Bullet cam was installed at 4 degrees retard and he couldn't remember why he did that, so no help there. The Bullet cam card said to install the cam at 102 intake centerline, and with an LSA of 106 maybe that's why it was in at 4 degrees retard?
