See if you can get a .010 feeler gauge in the spring at max lift in 3 coils for a min of .030 clearance at Max lift .. that cam has 360 lift you likely have coil bind . That's a big cam on a 4 valve need to know your springs installed height. Next break might be a dropped valve so I would check this
