Looking into getting my heads ported. What is the typical gain for 2.5 LS6 Heads? Right now with the mods in my sig I put down 390Hp/373Tq. My injectors are maxed at 104%, hoping to get some 35lbers soon. Anyway, my heads are bone stock 243's with Comp 918 springs. How bad are my heads and maxed out injectors holding my Hp/Tq back?

I'm no expert but without looking at your graphs to see when the injectors maxed out, I would say around 15-20 RWHP by porting the heads. Because the 243's flow pretty good as is.
You know how it goes, sometimes more, sometimes less. Depends on car/dyno. With you being an automatic, that's my guess from what you'll see on the dyno.
