Timing belts/sealing seals

Hello.
I was relatively new in the v8, but my thicker would need urgent new valve shaft seals and a new tooth belt as well as belt.
I'm thinking about sharing everything except the seals for the timing belt protection, but I just hope it can be done without it.
So as I understand, I would need if it were to be put on its luck only on special tools the,, counter holder 3197, or would I need anything else?
The camshafts have to get out so I can get free to the gallery.

PS: I take the front completely and I will leave me for about 3 days so that I can relax everything.
