Answer: only if I modify my intake, you have to use one from an ls3 since the rear ports are plugged and only need the fronts. damn, Google is good for something.

i opted to unplug my rear ports on my l92 heads and running the tubes on all 4 corners. rigged up a l92 & ls3 front setup pair to do everything for now, but the an fittings seem like such a cleaner setup

i havent installed mine yet, but there are a couple of different places that offer the blocks for use with AN fittings. The ones I got were not from a vendor here, so I don't think I can post a link.

The norotors link just confused me more... He said to run front or rear. Then someone said all 4... I'm just going to get 2 blocks and some an fittings and run it to the top of the waterpump

They are saying that GM Engineers/race teams have found that the 2 rear vents need to be blocked. The front 2 steam vents should be run to a surge tank with a pressurized radiator cap and then back to the radiator with a free flowing radiator cap installed.

On my L92 I clipped the tube with hose fitting and drilled and tapped for 1/8 pipe AN-4 90 degree fitting and then ran a steel braided -4 hose to the water pump.

just wondering if you happen to have more info on this?

I'm currently running 2 rear ports plugged, and just front crossover, but when I did manifold swap I was considering connecting all 4, but if what you say is valid, I will not...
