ITP's kit is really nice. You can do the fuel bowl delete but then you will have to put filters on the frame rail. The gain is better fuel filtration and for people running large aftermarket fuel pumps you can get filters that flow much more fuel than the stock fuel bowl.
If you are going to be staying with the injectors you have I would reccomend just the standard kit.
You would only have to add a post pump filter then if you did a bowl delete. It's really up to you on that one.
As long as you still have 160cc injectors the fuel demand isn't really going to change with a larger nozzle. Some have used the stock fuel bowl with hybrids and B codes of around 230 to 250cc's without issues. That's probably aproacing the point that a bowl delete would be a gain in fuel delivery.
