What are the best valves to put on for more hp?

 

If you're getting some headwork done, you might want to look into some oversized stainless valves, but you're not going to be able to just throw some new valves in and expect more power. Skunk and Ferrea make SS vlaves. If you're not getting headwork done right now, you might want to spend the money elswhere for the time being.

 

Oversized valves typically only make power in FI applications. For NA I'd stick with stock size.
