You could make a kind of spacer to go between them to keep the hose off the header. Something like a piece of rubber (exhaust mount type) with a couple metal washers on each end to keep thr rubber from melting. Might help. Like a rubber sandwich with washer bread.

Did you have this problem, and if you did how did you overcome it, I don't want to dimple the header if I don't have to, that could make things worse.

Please let me know, thanks.

Cobalt Addiction , mention they were to make adjustments for the header.. I hope you mention to him you were getting it for the HHR..
Anyways.. the large coolant pipe/line that runs on the back of the engine, needs to be adjusted for your header doesn't press on it when you bolt it to the engine..
So the 3-4 bolts on each side/end of the large coolant pipe need to be loosen.. once loosen, slighty put the header back into position, and feel along where it it touching the coolant pipe.. rotate the coolant pipe so the header clears the coolant line..
Once that is done.. retighten the coolant line bolts you loosen, and finish the install of the header..
I've had no problems since...
