first time using l92 heads and wanted to know what intakes will fit under the factory hood for a 1999 ss camaro and what are the plus with going with sheet metal intakes and will they fit under stock hood
The L76/LS3 intake and the Fast LSXR 102mm intake will fit under the stock cowl and appear like factory
You can also run a Single plane intake with a Elbow made to clear the stock cowl but there have been reports of the elbow robbing power. GMHTP just did a article on a 408 with L92's and the elbow made more power PEAK but loss a TON down low and in the mid range.
Sheet metal intakes can be made to fit under the cowl but from what I was told it would be more for track use then street use.

So what STOCK gm intakes can b used with l92 heads?

L76 has a press-in MAP hole and accepts the LS2 MAP sensor but the LS3 has a bolt-down MAP design and does not accept the stock LS2 MAP without some convincing
I run an LS3 manifold and all i did was buy another MAP sensor gasket and 'double up' on my LS2 MAP... crammed it in there and its been fine for over 3000 miles. others have done this with success as well.
