You've got a lot going on there.

First, they Alpha's strength is fine for a small block, but the 14X22 prop is way to much for that boat/powerplant. You need something like a 15X17. My experience with a wide number of props in the 260 with a SB is that Mercury's Vengeance works very well.

Also, I would not go messing with the cam and heads. Alot of research went into the setup the factory sent out. These motors have cams and heads very specifically designed for the application.

Put your boat's info in your signature.

The "260" I assume that is a 5.7L?
I also agree with Keokie. The 22 may be a little too much, but check here:

You may want to consider a drive shower on the Alpha for that application. It's inexpensive insurance for your drive.
