Well my friend you need to upgrade the Intake, get bigger fuel injectors or carb whatever you have., installing 1.7 roller rockers will give you more lift on your cam *its complicated on how it works but it will give you more lift*. Change out your cam with a hot cam. Port and polish your heads, or replace them with new aluminum ones. You can change the pistons and add more compression. I would bump it up to about 10.5 or 11
