Head gasket replacement on an a6

I have a spare d16a6 engine in my garage that has a blown headgasket. Im going to be putting this engine in my hatch because I broke a rod in my ZC. I was looking for a new head gasket and saw that there are two available for the a6. One says its used for normal replacement and the other says its used if the old one had a leak. Obviously, my old one had a leak but that one is like $30 more than the other one. What I want to ask is, is it really necessary to get the more expensive one or will just a normal replacement do fine?

Heres the website if you dont really get what im saying...

I would just go for a Autozone Z6 gasket, actually thats what i did get.

why the z6 gasket?

it is a MLS (metal) use copper spray too, helps conduct heat and seal. Raises the compression a little tho.
