Stock is fine if you enjoy changing the valve seals so much that you want to do it again at regular intervals. Otherwise, you might want to use positive seals instead.

Whats regular intervals? How long do you think its going to last? I went 100,000 miles on my stock ones before I changed them when I did my cam swap. It puffed a little oil at start up, but nothing major. I just went to Advance Auto and said gimmi the best you have in stock. Now I'm fine besides running a touch bit on the rich side. But I dont puff anymore smoke when I start my car. Anything is going to be better then what he has in there now. Hardest part is going to be changing them. But with the right tools and an air compressor, its not that bad.
