I tried posting in general tech LSX, so i'm gonna try here. i found a good deal on some stock heads, casting 12562317. i've read up and it says they're from a 6.0L '01+ engine. the chambers are 71cc instead of the 66.7cc on my current heads. I was wanting to buy them and and maybe build them up in my spare time.
So my question is, first of all, i need to know if it will fit alright on my camaro!

Then my other question is will it be worth the buildup horsepower wise?

THEN if all is good, what are your recommendations for a build-up?
as far as the rest of the motor, i plan on keeping it stock stroke and bore. i may replace some of the bottom end, but all will remain stock specs. i need advice in what to do to the heads, porting, polishing, which valves flow best and take the harshest beating. any ideas for what cam specs to use if these heads work out?
i'm still very much learning, so thanks for the help!

They'll fit, but you're going to lose too much CR if you aren't building a forced induction setup.

From the Chris Endres book "Chevy LS1/LS6 Performance":
You might want to pick up a copy of the book. It has a lot of info on LS1 buildups.
