I'd say you should keep it around 10.5:1 comp if you wanna run pump gas. You could probably get away with a little more if you bumped the timing back a bit. But that's just a trade off...more timing, more power...more compression, more power. Doesn't really matter. As for 11s, I think you'll need a bigger cam. I'd also go with a bigger 75mm throttle body. I mean, you've got a 73mm Mass air meter...why make it choke down at the throttle body? Part throttle conditions might be a bit touchy, but at WOT you should make more power.
