Will this combo get me 13's??

[Stang_Crazy]

I plan on having: Electric fan, Aluminum radiator, Pulleys, 75mm MAF, 4.10's and 245/45 Nitto DR's. I know the radiator and fan won't net alot of horsepower (if any) but they will help when I add heads next winter and they should keep my car running pretty cool this summer.

Are headers next on my mod list?? I figured with the MAF, and exhaust I already have, the headers would be restricting some of the increased airflow.

So could I hit a high 13 with these mods?? Feel free to make any suggestions about things I should change (maybe 3.73's instead of 4.10's)
