Droop, Diverter help

I have a carrera 205 elite I was thinking about putting a droop and different diverter on. I also have a ride plate, and shoe I could throw on if that would help any.
Anyone know how this may affect my boat?
Any other mods that may help performance will be welcomed. I do have a set of oval port 049 heads that I am going to port and polish, any suggestions on a good manifold, and cam lifter set up?
Indmar 454, snails, Berkeley pump, with AA impeller.
Timinator I know you have played with one of these things. (any suggestions?)
Here is a couple pics of the droop, and diverter I want to use.
Thanks to everybody.
