If they fit, the manifolds really do flow pretty well for what they are. Headers will still perform a little better, particularly up at the high end. A good long tube will also boost your torque, but with the torque these motors build, you wouldn't be dissapointed with the stock manifold. The O2 sensor placement may be an issue. I don't recall where everything is in your car, but make sure the O2 clears, and you should be fine.
another thing to consider is the sound of the car. I think the headers sound alot better. Im running manifolds on my 69 camaro and it just doesnt sound like it did with headers....but its a totally different engine too!

I think mine still sounds "sort of OK" with cast iron manifolds....

If you're considering shorties, this might be worth a mention. Summit Racing in Akron, OH has had a pair of LSx truck headers on the clearence shelf for a few days now. I saw them on tues. then on Friday. They were shorty-non-coated display items for $100. Not sure if they'll phone-sell / ship items from the clearence rack, but a "sale is a sale" I'd think.

From everything I have read shorty headers are not worth it if you have 2001 or newer f-body manifolds or vette manifolds. The dyno tests in all the car mags show the power output as being virtually the same.
If you go with longtubes and delete the cats it is worth it.
