SS Springs on 75 Duster

yeah...i must be senile to work on all this crap.....anyway
Fired it up this afternoon..,,,,had a noise in the valve train on each side...after just buying new pushrods and hold downs...I thought WTF now
took the covers off....ran through the valves....nothing.....ok...i got some cheap *** chrome valve covers on it....fire it up without valve covers...no noise...
swap out covers for a set of the mopar cast aluminum valve covers.....fire it back up....did some carb adjustments.....then it ran out of gas.....
at least i am moving forward at this point...
