Although I chose AFR as the best heads, I'm actually running the GT40X turbo swirl heads on my car with an E303 cam, and an Edelbrock Performer intake. I am pretty happy with this setup as the car runs very strong for what it actually has. A lot of people willl tell you that there are much better head and cam choices than the Ford Racing stuff and they are right, but I definitly think that for the price, the aluminum GT40's and alphabet cams work pretty decently when set up correctly. But if I had to build a new motor, I would probably lean towards AFR's. Also, even with your car being a daily driver I would still look into a mild convertor, such as one with maybe a 2600-3000 stall. I have ridden in cars with built motors and stock convertors and it really takes away from the engines potential in my opinion. But what ever you decide to do, good luck with your build. O0
