i also forgot to mention i leave at 4600 and shift at 6800 and it drops to 4800 on the shift...converter flashed at 5300 and is the same one that flashed 6200 in the superstocker.so that is one problem ..it has 14x32 HOOSIERS.....thanks for all your comments.

Danny,

I would say thats a pretty good 60 ft time given the combo that you have in the car. I would say you need more gear in the rear. 586. The 180 low is killing you. You need a 198 low gear. The heads are probably quite a bit bigger than the old super stock heads and thats why the converter is not flashing as high. The power range is higher with the aluminum heads.
The weather will also effect the 60. Hot and humid the 60 will drop off.
Pump up the tires where you get a little bit of spin. if that picks up the 60 and overall et than you need to make some changes
