Typical gains with LS2 heads? Untouched LS2 heads to be exact. I picked up a pair for 300 bucks along with a lid and a dual dual catback. Can i expect atleast 20-30rwhp out of that combo?
LS2 243 heads will lower you compression ratio so you should have them milled down and they will be a nice addition to your LS1. Once you get ready for a cam you should do the heads at the same time to save money. Good luck, John

Heads - 300
Lid - 90
Filter - 40
Dual Dual - 300
730 Total. I wanted the dual dual at ALL costs. Hopefully i'll be able to pull 12.7's with these mods

Since they were used, my advice is to have them checked by a machine shop, refresh the valve job and change seals.
After that, your next mod should be a tune, that alone can net you more power than all your mods put together.

Thanks predator. I sold the heads to a friend today for 350. 
Got to thinking as much as i want to tear off the heads i don't want to do it without adding headers at the same time so i can pickup another set of heads down the road.
SO for now the Lid, Dual dual and an Off road Y will be only going on the car. With cooler weather i hope i can pick up the .3 tenths to get into the 12.7's
