An increase in compression will mean the need for premium gas. Also with most PCM'* you will also need to run premium gas. And with a cam, you will pretty much need a PCM, meaning you will need to run premium gas.
It only costs $.20 a gallon more and you get better gas mileage with it.
Nice topic with lots of info. I am thinking of doing the Level 2 kit but wonder about the 1.90.1 rocker arms after reading this thread. Intense claims 30 extra HP which our transmissions should handle.
The 30hp gain they talk about there is for a supercharged car. (which is still stretching it a little IMO) L36'* generally see about half the gains the L67'* do with high ratio rocker arms.
Based on what you say it sounds like you want your car to be a solid mid 14 second car. That will mean quite a bit of work at your weight. My suggestion would be:
ZZP GT1 Cam
UD Alt & WP pulleys
Then see where that gets you and go from there. You might want to scratch the cam out though and replace it with rockers because a cam install is not a simple job, and with all the supporting parts you'll need will actually end up costing around $600.
