Header clearance

[John]

I wanted to get some opinions. I noticed the driver side header, one of the tubes looks to be touching or just a hair from touching the area where the 4 brake lines come together. I believe it is creating a rattle from time to time (mostly as I come to a stop I notice it). My Question, what is the best way to resolve this issue of clearance at this location? and is this a common issue with SM chevy headers?
