These are Crower Springs that the engine builder put on 7 years ago. The 596 heads were completely rebuilt and I really don't have many miles on them. They had the clearance the 273 rockers that I gave them originally but when they shut the engine up they said some of the adjusters weren't holding and that's when I had to take them off and put locking adjusters on.. that was 7 years ago though when parts were plentiful and like I said I foolishly sold that set...
