Upgrades to a Blue Merc 500 EFI.

Where do you start on this motor, It has 75 hours on it since new and makes good power now but what can I do to it to get things jump started for next season? Have any good ideas, within reason . This will be my first efi boat motor.

Heads,Cam and 3.3 whipple..
probably dont need the heads but thats what I did..
took me up to 750ish on a carb motor..
I ran it hard for a year and took it appart to make another motor.. but when we took it appart it looked good still.
