Does anybody happen to know if there is a difference between the 430 valley pan and the 455 valley pan? I have a 430 and on the heads there is an opening on the top in the middle (about the width of a finger and about 2 inches long) and on the valley pan there is no cut out there? Any ideas?
Thank you in advance!
