Upper control arms are touching the bump stops

I have a 1975 dart swinger that is a drag car, will never see the street. I raced this car about 6 years every weekend when it was fairly stock. Its has been in my garage the last 10 years getting completely redone. The front end was rebuilt the last year I raced it so I left it alone. I noticed the upper control arms are sitting on the bump stops. The bump stops are flattened like a mushroom. I have no travel, and there is no room to even remove them. The car is completely done with engine and trans back in it. I removed quite a bit of weight from the car and was wondering if this has caused this problem. Maybe ride height is up. Any opinions?
