Default LS6 manifold back to LS1 manifold...how much power am I losing?

Another member sold me a broken LS6 manifold, I'll leave the a$$hole nameless, and it was cracked in the back. Patched it up pretty well and seemed to hold but in the long run it caused a major leak on my car and idle problems so it had to be removed. Anyways I had to go back to my LS1 manifold for right now, what kinda power am I losing going back? Mods are in sig below. Guessing I am choking the cam up with the LS1 on there right?

Not sure, I know I am giving up decent gains considering I have some nice bolt-ons to compliment the manifold. Gotta save up the $425

Let me rephrase.....how much HP am I sacrificing until I swap out and get another LS6 manifold.

Around 10-15hp. Its a good mod but IMO is overpriced for the gains. I like Mods that are around $10 per HP. Used headers,cam,lid,TQ converter.I wont pay over $200 for one,thats why i wont ever get one.

Not buying used again, SLP non-EGR is $423 shipped to my door, that's the route I am going. Sucks cause I know I am choking my cam, and as stated it isn't cheap for the return you get.
