4.6 PI Head Removal

[Popacap]

I am a newbie so feel free to pile on with suggestions. I have a 2000 Lincoln Town Car Cartier. It has the 4.6 Romeo NPI engine and the original all plastic intake. I went to the local Pull-A-Parts and removed the PI intake from a 2002 Lincoln Town Car.
I realize that the intake will require some RTV in a couple of spots so I am thinking about going back and getting the heads from the junk yard too.

Do I need any specialty tools or pullers to get the front engine timing chain off in the junk yard in order to get the heads? Do I have to remove the harmonic balancer in order to get the heads off?
