I don't understand your question. I think the answer is that typically, FI motors run 8.5 - 9.0:1 compression. The stock CR was 9.4:1 in '04, if I'm not mistaken, and they were identical to '03.

Comp 270s are good cams for NA and you will make a bit more power over stock cams with a blower but nowhere near the amount of power you would make with a blower cam. You lose way to much boost with a NA cam and it brings your MPG down alot.
