Ok just want to make sure everything was thought of.

The forged stuff is a bit more forgiving that is why it's recommended. If you have a good tune then you can run cast crank and rods, even pistons, but probably not worth the chance.

Once you get into quality forged stuff the OE block then becomes the weak point on a FI motor. You should be able to run 600 hp/lb-ft without a problem.

I would shoot for 9:1 CR it will provide a bit more driveability for the low end.
