VP 3.0 water on top of heads

[Jimleopold]

I have a VP 3.0 gs. 1999 I think. I replaced the exhaust bellows at the riser last year. I noticed that it wasn’t the diameter a in the center where exhaust and water mix wasn’t a big as the original. I have been getting water on top of my cylinders since I changed it. Enough to cause hydro lock! I have to take out the plugs and turn it over to get the water out!
So my question is, does the 3.0 require a larger diameter in the center of the bellows than a 4.3 or different years?
And yes the gaskets are good and I replaced the exhaust manifold earlier last year so that should be ok.

In addition I just realized that I installed the restrictor at the tier per the engraving, and just saw that the manual says the opening should be towards the engine. So that’s an easy fix but still not sure if the diameter of the rubber hose could also be causing the water on the heads. More on the back two but all of them.
