We're not talking a shortblock. Shortblocks have rotating assemblies within - crank, bearings, rods, pistons, pins, rings, timing gear (usually), cam etc.
Personally I would not choke it with a set of LS6 heads when far better flowing heads are available.
Yes, some of us have read associated threads on LS1Tech.

I can't say that I understand the hype of the LS7 engine. For $14K you can easily build an LS1 to make more power and be just as reliable and streetable...and not have to deal with any of the PCM issues

You left off the crank, titanium rods, manifolds, and ton of other parts. Quotes I get for a 427 is 25-30,000

Every thing is already balanced you just need to disassemble and reassemble.

none of that pushes the price tag to $30K, you might want to make some more phone calls and or price things out for yourself.
