would be 1 step or so above stock? building a 5.9 for my dart and will have to go thru the cyl heads but will not be changing cams at this time. if i have to put new springs on the heads, i would like to go 1 or 2 steps above stock at this time. tia. rick w.
 
There aren't a ton of drop in options for the Mag. I have the Hughes springs that 318willrun mentioned with their SER0814ALN-14 cam. I have spun my engine past 6000 rpm and didn't feel any valve float.
