thicker head gaskets, methanol, & a good tune with limited boost could work....
engine goes south and you build your new FI focused build with the coin you were able to save by not spending for a half job now.
Just my 0.02...might not be perfect...but an option nonetheless.
If used parts were worth anything I would give different advise.

...been seing this in a few places re: re-sleeving the block. I have been running an LS7 block for some time...even had a rebuild on it, with no problems. How many guys have been blowing thru LS7 blocks? Not sure it the block is a real issue up to monster hp levels. Maybe applicable/maybe not...but kinda' of reminds me when everyone was advising guys to go wth new cranks when the LS1's first came out...years later, guys are running 8's and 9's on the stock cranks. I do agree on the pistons though.

We have several 650-700rwhp bone stock LS7's roaming around that way. Granted it is discussed that there are no guaranty's at that level, but they are all happy so far, and for some time now.
Of course 17-18lbs on a stock piston might be part of the problem, but it did take almost two years of hard racing at that, and we have only broke one LS2 C6 so far.

So, all of the speculation here, no one has yet to fail a stock LS7 piston?
Sure, going to a forged piston is correct, but everyone here is crying wolf, yet no one has seen the wolf?
All of my builds, save for cars on the gates only get 100% built engines, sleeved blocks, etc. All of them have made over 900 rwhp.
Im not in the business to chance someones engine, unless its their prerogative.
Guy simply asked if there were larger chambers available. I have that. Everyone else is screaming pistons

There was a customer of ours in Puerto Rico who was a 800 or so on the stock LS7 and it let go eventually.... i'll try to dig up the specifics...

Not boosted, but still a failure. And also another one in the linked thread.

FI tunes are usually WAY more conservative, than a track car on the Ragged edge.
So now that this thread has derailed, whats the OP going to do?

Further, lowering the compression a half a point at most will net zero gain in reliability or longevity given the same result in power output.
I'm sure you agree with that.
