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.
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.

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...
