Baffled by apparent reversion issues with Lightning headers and mild cam

Thanks Buck - planning on Friday after work, or possibly Saturday if it rains. Motor was sat down in the boat last night. Going to hook everything up this evening and get the drive back on it. Exhaust shop is going to weld a 3 1/2" diameter pipe in just upstream of the water pipes that will flare out to the 4" inner pipe diameter. The idea is to let it act like a turbulator while also directing the water spray back to the tips. Going to let it extend out the back from the 4" inner an additional inch or so for good measure. I think that should solve my problem. I'll update when it happens. Thanks for the advice and encouragement guys.

I'll post up some pictures when I get them back. Makes me wonder if this would help out the folks who were having issues with killing O2 sensors on their Lightnings.

I do not believe the boat exists. 10 different threads on engines but not one boat thread! We need proof of life on the boat!

I think the old tub can be seen in the background of a couple of the shots. Definitely retro-ghetto-redneck.

The Fix is in...
Here is what we came up with. He let it run long so I could measure how much I want to cut off. Going to let it run about 1.75" past the original collector on top and slash cut it down to about 1" past on the bottom. He also gradually flared it from 3.5" up to the original 4" inner diameter for minimal disruption of flow. Might add a bung later to bleed off any excess water, but I think this will do a good job of diverting the water downstream and prevent it from getting sucked back in. Hopefully this will fix my problem.
Back side - thought he did a nice job gradually flaring it out to meet the original pipe:
