Timing set opinions anyone....

If i need stiffer springs then its no peoblem to get some, the heads are very low milage though so i dont really know if ill need new ones. And as far as aplication, im building a street brawler that i can cruse around on the weekends and run it at the drag strip occasionally. 72' Duster w/73' 440, Holley 750 double pumper (might be replacing that but well see), eddie victor intake manifold, long tube mandrel bent headers (dont know the brand or exact size because the car came with them on it), and flowmaster super 40s.
A727, reverse valve body, 3800 stall converter, and an 8.75 rear.
