I do mine horizontal all the time in my pk100 they turn out great, the only thing i do is rotate the top and bottom rack about half way through the cook time just to make sure they cook even. I lay them across the grates.
@MTArcher They are fairly similar but the Mexi chorizo is the right choice if you are ooking for something closer to the chorizo most of us are familiar with. The regular chorizo is excellent and can be used for making what we consider chorizo but that is the one that someone would use if they were to dry cure the sausage.
