I have a 1988 Mustang lx 5.0l 5spd. Going to be a street machine 98% street driven 2% track, Currently building a 393 carb to Drop in, I just am unsure on which heads would work best with my combo, afr 185s? 205s?? or something cheaper with similar flow would be great! wanted assembled heads also. If you have any input in the components i already have let me hear it! Also any hp guesses?

Heads???

 

if you are gone with the AFRs I would not go smaller then the 205s and that is the same on any head as far as runner size. IMO
