What is a easy way to remove it? or do i have to take the oil holder thing out to make it easy?

Yes. Especially for a stock header, the oil tank has to be moved (or removed). Good time to change the oil, filter, and clean the strainer.

I've never removed the oil tank to get a header off of a 400ex.

Interesting. I was just going by the manual & my experience.

It (stocker) nearly came off, but there is no way in hell that the WB header was going IN with the tank there.

I took off my stock pipe and installed a white bros. alumium pro system without ever removing anything other than the the plastic. Take the sleeve off first then take the head pipes off.

What welds are you talking about that you are going to grind off

The welds inside the header where the flanges are welded on. You will notice a slight differnce but nothing worth bragging about.
