What gains can I expect
What gains can I expect well I took the plunge and bought me a set of LS7 heads with titanium valves extreme springs and a ported LS7 intake to replace my stock L92s with L76 intake. With the new LS7 heads I have to upgrade to 1.8 rockers which will change my camshaft lift from 605/596 to 640/631 lift the duration is 238/254 114 lobe sep. I am getting the QM600 possibly soon but it seems extremely close to my current cams specs. The old setup made just over 505 rwhp with the non ported L92s and stock L76. Also got a set of CTS-V high rev lifters to replace my stock LS1 lifters and a set of Manley push rods as well.
You can get an intake flowing better than that too...

Having P&P heads, I would look into getting a ported LS7 intake. Make the most of what you already have.
As far as me guessing at how much power you'll pick up, sorry man, it'd be just a guess.
I wouldn't be surprised if you see 575 rwhp though.

My intake is ported already and my TB is a 90mm but looking at a 100mm that I know of someone coming out with and I may test it for him. With the extra lift the better flowing heads intake and bigger MAF sorry forgot to mention that I also am changing from my stock 78mm to an 03 Z06 85mm unit. But if I am in the 560-580 rwhp range I will be happy.
