Just thought I’d throw out what I read. I sure didn’t do any extensive testing on it. I run the old 4 port LS1 vents because it’s what I had. Seems if 4 port was the best method the gen4 stuff and race teams would be using it.
Also the coolant system is NOT at a constant pressure at every point. Depending on the size, shape, and number of the coolant passages, pressure will raise and fall and the fluid will speed up and slow down. That’s Bernoulli's principle. 2 smaller passages branching off of a larger supply will net a higher pressure than say 4.
I can post up pictures of 2 point vents as well... what does that prove? What kind of pump is that engine using? what kind of pressure do they run in the coolant system?

So this caught my attention:
The proper setup all my LSx racers are using is, assuming the top of your radiator is below the steam vent port:

The only thing I don't understand is what he means by "open" radiator cap? Im under the impression that the radiator cap needs to be elimated or plugged if you will. Allowing all coolant to be entered into the system Via the expansion tank.

The vent system is for clearing air, it does not change engine pressure if used with collection block as the return flow does not change. The air will clear from the heads with 4, if you only use the front you have the potential for air to be trapped in the rear of the cylinder heads. This causes problems in the rear cylinders in my testing, mostly showing up in cyl 7 damage.
The C6R engine uses a different coolant flow path than production engines, it is very nice!

yea the problem was, showing off and running without gauges
looked over the data, tune looked really good at around 8-10psi but when we got into the 14+psi it was just to much
redesigning the waste gate, and doing a bunch of testing before going out and trying to show off
