Flooding is when gas overflows from the carb fuel bowl.
Most likely you're seeing the water produced by combustion. When the exhaust system isn't fully warmed up, the water vapor will condense before it gets out of the exhaust pipe and drip. Open headers will make that worse.

Re: engine flooding
make sure the fuel pressure is not more than 5psi.

Re: engine flooding
Sounds like a fuel pressure issue...do you have a regulator on there? Is is a fuel injection pump?
