Friend built his 34' boat a few years ago with a single engine in mind.We've opted for the ZZ572 engine with Stellings dry exhaust.It worked great until the inner jacket at one of the exh flange cracked and doused the exh valve and dropping it.We had to scrap the dry exhaust idea and had Eddie Marine fab a s/s wet one to our spec, mounted on the EMI aluminum unit.We had to get the risers taller than the stock units readily available to stop reversion. 500 hrs on the engine and boat ,running top as a commuter on weekends.

Flappers will help with water ingestion when the boat is sitting at the dock/mooring and waves come over the pipes but they will not help with reversion while the engine is running.
If you have gills, I really think you're fine Josh. Your cam is smaller than the 731 the HP 500's had and they were built originally with Gils and silent choice.
