Yeah you can run stock valve train stuff, but it's said that it's recommended that you change springs and get rocker arm stoppers. The rocker arm stoppers you don't really NEED, but if I were putting these in my car, I'd probably upgrade springs.

And they're clean as can be, sorry the pictures freakin suck. My camera on my phone doesn't have auto focus so I have to sit SUPER still. lol. I can try and take better ones though.
