Default ls7 potential

Another hypothetical situation here. How much are the ls7 ported heads capable of n/a. I am trying to figure out what I can produce within the limits of the parts I already have. Right now all I have is the block and pistons. The block is a 4.11 bore and the pistons are a set of Diamonds with a -7 dish. What are some of your opinions? I am looking at compression between 11.8 and 12.2 or so. Really leaning towards a sheetmetal intake. Car will not see much street duty, but I do want to be able to drive it to local car shows and such. Maybe a little late night fun too I don't have a problem with going solid roller, or almost anything else. My goals are well above 600 rwhp, but the most important is very solid 10's at the track. M6 car that will have a 9" and probably 4.10 or deeper.

With a sheetmetal intake, larger throttle body, fully ported heads and wild cam 700RWHP should be a slam dunk.

I thought the minimum bore size for LS7 heads with stock valves was 4.125"?

4.10" is the minimum.

Corvette Doctors just finished a Z06 w/ 13:1 cr using the stock LS7 intake and reworked LS7 heads. It made 640+ rwhp thru the stock mufflers w/ a moderate cam.

I should have been more specific. Car has got to run on pump gas. If I can get 650 I will be pretty stoked.
