A more aggressive cam will really hurt you gas mileage. I don't think you'll be able to maintain 20mpg with your gears and a hefty cam like that.
Plus with a cam like that on the TFS heads, won't you need to do some serious piston flycutting?
You need traction man, not more power. Hehehe, spinning through 3rd would now be spinning though 4th.
