I upgrade tons of 502 Mags. I don't offer a "package" per say, because it is inevitable that everyone wants something different. I can however, upgrade your engine's looks and performance from mild to whatever you can dream up.
Give me an idea of what you are looking to accomplish. What is your hp/ speed goals? What type of boat? How fast are you looking to run? How fast is it now? What is your ballpark budget?
The answer to these questions can give us a really good idea of the best course of action. Give me call if you would like to talk about it. Thanks

By the way, these all started life as 502 mags. I also added some pics of an extrude honed intake.

Vortech Marine makes a nice little package that has new air cleaners, ignition ,fuel regulator and re-programed Ecm's that will give you around 25-30 h.p. per engine. They use quality equip. like MSD..... air cleaners are really trick !

How much power do you want?
Lot's of people advertise things. Let's see, you can get some of those fancy air cleaners and that will get 20 hp, exhaust = 30 hp, expensive spark plug wires = 10 hp, fancy oil = 10 hp. Wow, that is 70 hp. For a few grand that will run with a 500 EFI.
Unfortunately it does not work like that. The only way to get real power is to do the heads, cam, exhaust and have someone reprogram the ECU. The small time stuff does not hurt and may improve throttle response but that is about it.
Eddie Young here does great work and will set it up the way you want it. He took mine and made BIG power. Mine has boost, so it is a little different animal, but he used my 502 as a base and turned it into a piece of artwork. I have 3 seasons on it and all I do is change the oil.
