TPiS Heads?
I've been in the market for heads lately, and the AFR's just seem so outrageous. Upon searching for a cheaper alternative, I came across these:

are you dead set on replacing the heads? If not, you might want to consider the following...
elliot port works (ports the stock heads)
Advance induction (port the existing heads OR purchase Trickflow castings ported from them).
Otherwise, Dart heads are certainly a reputable set of heads!

The other options are well worth considering too. Those Darts you linked looked to be priced right...probably where AFR's should be. Certainly that's near their L98 head pricing.

Take your time and research on head selection. In terms of performance and reliability, this is one of the most crucial mod decisions you will make. There are alot of good options out there, but you really want to avoid a bad one. While a top notch set of heads will set you back, the reward and peace of mind will be worth it.
Most importantly to know going in is what you want out of the heads. Performance is many different things to many people. Do you want top end, low end? How do you drive? Do you go to the track, drag or autocross? What rpm range do you spend most of your time, and where do you want that power? Not to mention that a poorly constructed head could be the end of the entire motor.
These are all things you probably thought about. But considering the expense vs. reward factor, you may not want to cheap out on this one. If a top end head is out of your budget, than a good porter can be your best friend. JMHO

And another side thought: how would these fair?

I plan on running the CC XFI 467, and its ideal operating range is 2000-6000. I don't plan on taking the car past 6k, so with that in mind, what would be a good bet? I want it to be STRONG from 4300-6000

If you are going to use LE why not get one of his custom grind camshafts that are matched to the heads.

I got the Elliot's LE2 in my LT4 and it is a beast. My LT1 is asking for the same recipe

Great point. If I decide to go with the LE2's, would it be advisable to go with the cam he says is comparable to a XFI 467?

Ya mean what PLRX said 4 posts above isn't enough? I think Cuisinart's point was to ask you about goals. Is this for racing where every 1/10th counts....or for fun?
If the later, you'll be fine. FWIW, I think BigGrizzly also had a fairly big write-up on his LE heads.

I have TPIS/AFR's on mine.....I think they are the 187 cc chamber variety whereby TPIS did their own porting on them......I bring that up since TPIS has done plenty of research on L98/LT1 engine types.....looks like a good quality head for the money, IMHO......do they have dyno numbers they can share?
....call them......
