Ported FAST/ 1 3/4 lt kooks catted y? I am putting a ported fast 90/90 and 1 3/4 longtube kooks headers & hi flow catted y pipe on my stock bottom end car today. The car has the stock ls1 intake and stock manifolds w/ cats. What do you think the gain will be? Mods are ported 241 heads, 224/220 .581/.581 lsa 116 cam, lid, pulley, borla, & 3800 stall. 
The car will get retuned next week. No dyno numbers before.

Well what numbers is she making now ?? Kind of hard to guess what she will make without knowing where you are at currently.
With that being said I wouldn't be surprised if you pick up 40+ rwhp. The ls1 intake flatout sucks, and jumping up to headers will really improve your cars ability to breath. I hope with tuning you make even more. Good luck bro.
