ZR1 with headers and tune...
Vette Dr's has put on a set of headers and a "conservative" tune on a ZR1 that has only 200 miles on it and here is what they got (598 hp, 557 lb/ft).

Very nice - "back in the day", I remember the rule of thumb to be that headers add approximately 10% horsepower..........that's pretty darn close to that!

Is that good or bad? I read they were 638 stock. But what do they get to the wheels stock? I'm assuming that tune and headers is to the wheels?

I think if everyone pitches in some money to me through paypal, then I would buy one from the local dealer and slap a huge LS1.com on the side. Everyone of course would be more then welcomed to come down and drive it.
