Default back to stock cam, but having major issues

I put the stock ls1 cam in my car. its a 370 iron block with stock ls6 heads, prc dual springs, 7.4", stock pulley, ls6 intake. I did the swap and now the car wont idle over 500 rpms. Its running super lean too. Any ideas where to start? Ask what you need to get more of an idea whats going on if ya have too.

If you have "TRUE" LS6 with light valves, your pushrods are too long.
You'll need 7.350s
You valves might be hanging open.

However, the super lean issue makes me suspect a vacuum leak.

you should probably swap back in the stock springs or at least ls6s.
