Want to install headers but which one

I am going to use these when I put the motor back in.
They look to be the easiest headers to install.

Fixed the link

Can't imagine any being easier than these. They are even prettty :)
I'd be going with them, but don't want to give up any HP so I'll stick with long tubes.
