LS6 Heads with G5X3?

LS6 Heads with G5X3?
I'm throwing in a G5X3 this winter along with LS6 intake, long tubes, duals, etc... the whole works. The goal was 400+rwhp and to break into the 11's at 120mph. I'm now thinking of maybe going a little step further and just throwing some heads on while it's at Rapid. I really don't want my car to be too radical since I drive it 365 days a year.
But If I could get a pair of complete, unported, LS6 heads for a decent price, how well would they work with the cam? I'm going with a 114 lsa, so that wouldn't matter for the heads would it? How much more power would you say I'd see with the heads? I'd like to think 425rwhp with the heads on top of the G5X3...

i would definatly get them ported...i'm getting mine ported and i'm going to be driving mine 365 days a year as well...i don't see any real reason besides money i guess that you shouldn't port them...however your power estimates seem about right to me with unported ls6 heads...

Oh well, the results will keep me happy
Oh, one thing you're not considering for daily driver duty is that I have snow and freezing temps here! If I were in Florida, things would be a bit better

It's made by LG Motorsports. Here's the "known" specs...
2??/2?? Duration & 600/610 Lift at 114 Lobe Seperation.
It's bigger than their X2 which is 232/240 Duration & 595/608 Lift at 114 Lobe Seperation.
The X3 is a roudy cam, makes big power, and IMO, is very streetable.

Here is a graph of a Z06 corvette with just headers, G5X-3 cam and full mufflers.
Just as they drive on the street. No ported tb and full belts and stock water pump. 160 thermostat and stock intake. If you mill them you will just have to fly cut but you can clean them up with a .005 cut with no issues with stock valve size.
Have fun. You will love them.
