I did get it dyno'd. Peak #'s aren't that high, but look at the torque curve, and lack of significant top end hp falloff. With cams It's going to be a whole new beast (for maeda to make fun of). hahaha
Rough cost was ~930 for the ITB's, MS, and all the other junk that goes along with it. I'm selling my current ITB setup, as I'm making a new one. So if you are interested (seriously), PM me. I'll put them up in the FS section in a couple weeks.

Companies that make cams for KADE's:
JWT Gude PDM Racing Crower (used to, can do custom grinds too) And some more I'm sure. But none reputable I can think of... A note on valvesprings and retainers. It's been confirmed that CA and KADE valvesprings and retainers are the same. You can use CA springs and retainers in your DE. I was talking to a very reputable source that said that CA and VG springs and retainers are the same. So if this is true, for valvesprings and retainers CA = KA = VG. This means lots of choices. I'm getting some cams (JWT) in the next week or two for my engine. I should have before and after tests on the same dyno with the cams. I'll also play with velocity stack length before and after, to help get a better idea of ideal runner length for the two different sets of cams. Oh and SOHC pistons in a DE. I havn't tried it out yet, but It is more likely than not that aftermarket cams in a DE with stock sohc pistons will not work together. Will put the valves into the tops of the pistons. The valve reliefs in the sohc pistons do not line up with the valves in the DE. I've run this across a few reputable nissan engine builders, and they also highly doubt that cams with much higher lift than stock will work with stock sohc pistons. And because people alway ask... The highest hp N/A KA24DE to date puts down 365 flywheel hp. I forget the torque. 290rwhp. I want to say 25x rwtq, but don't quote me on that. This engine is used in the Nismo baja truck things. They see 11,500rpms in the air. You can buy them with a few hours on them now and then for a pretty penny. Call BS if you want, I've talked to the builder myself.

I also wanted to add that since the KA doesn't have a fully counter weighed or knife edged crank that there are affordable alternatives.
Did some research on crank scrapers found that this company makes them for the KA... http://crank-scrapers.com/prod01.html Some people can look at them and think that they are worthless, but it is to break windage in the crank case, and increase HP. I am not going to say that it is any type of significant HP, but for $50 and a 3HP gain at peak I wouldn't mind having one. Especially since people have claimed that it increases rev as well. If ecu tuning and ITB's isn't your thing,(although I do plan to do it in the future) you can just have the TB bored, and ported from www.maxbore.com. RBS14 mentioned a diverse amount of cams available, I believe the im Wolfe is the best streetable cam on the market(although it cost the most) Great write up RBS13.

I am planning on building the KA and staying n/a. I am shooting to go past 200hp, however I was curious on something. How much can the stock ka24de cams hold? Should they be upgraded right away or should I save it towards the end? If so, what cams are reccomended?

there's 95% of the power curve (everything but WOT) that there is no quantitative way of representing. Not to mention response. Instant power! that's where the ITB's really shine. It's just one of those things you have to do to appreciate. Just a dyno chart won't convince you. With cams I got about 170 to the wheels with real tuning (timing). But now it's boosted so it's a whole new game.
