Ring gap

What is the ring gap for a stock 350, chevy, the engine is being built for a race car. got the rings the other day and tryed to slide the pistons in and it took a lot to get one in. so i pulled it back it was so tight that it took the hone out of the wall so what is the right ring gap for the 350
