Rick, If you are really concerned about reversion and the choice of cam you are putting in your engines, then contact RMBuilder/Bob Madara of Marine Kinetics in N.Y. (585) 654-8583. He will take all of your engine's components and match them to a custom cam profile designed specifically for YOUR engines and what you want to do with them. Bob is one of the country's BEST "go to" cam experts you will find...especially for marine offshore hi-perf applications.

Good idea not to be aggresive with the cam if in doubt. Were does the water blend with the exhaust? I have the EMI's with long risers and the water blend a few inches from the end. I have no experence with the Gills but those look similar to what I use.

I really don't think you will have any issues with the Gil's. They are not anymore prone to reversion than any other wet exhaust.

Blown engines are different. Not as prone to reversion.
