Get a light port and polish, and a 3-5 angle valve job if you are shooting for 300HP. YOu'll probably need some long tube headers too. I think 300HP is possible with the stock PI intake, but you might need a Bullitt intake also.
11:1 should be fine with 93-94 octane. You should have a good dyno tune performed though. 11:1 will be a bit much though if you plan any forced induction. You could always have the heads worked to drop the CR if you plan FI in the long term.
