I searched and couldn't find anything about this. I just got an AWR header and in the course of installing it, I noticed the lower radiator hose is very close to one of the pipes (on the order of 1/8"). Anyone who have this header installed do anything to change this, or will it be fine? Thanks.
 
Pics of problem.

That's good to know about chief, I've been considering buying some of those for a while now.
 
One thing to keep in mind, while researching this I have found there were a couple of different types of AWRs made. It seems the main difference is how the pipes were run from the engine to the collector (on some, the 2-3 pipes were run closer to the radiator, on other the 1-4 pipes). I have not found any note of anyone else running into the problem that I have. From the lack of response on this and other forums I am not sure of how many people are running this header.

I wrote to AWR and asked them in case this was something they provided for when the header was sold new (I am at least the third owner of mine). Tony was very prompt in responding and said they could try to modify it for me if I wanted. He recommended using some header wrap tape and/or stainless sheathing on the radiator hose. After looking closely today and taking some measurements, I am going to try either getting a new hose that will have bends that will allow it more clearance, or cut the stock hose and insert a section of pipe that will accomplish the same thing. The stock hose has an unnecessary kink which is what puts it too close to the pipe. For now I put my previous setup in, when I have some time to spare I'll take the car out of service, pull the hose and take it to a parts store to see what I can come up with.
 
My AWR header is the same way. It has been this way since day one. About 5 years. No real problems yet. hehe I used header wrap, and also used the stainless tape. My header actually touches the lower hose. About every year I replace the wrap and the stainless tape. I think it would be best to replace the hose with a steel braided one.

Thanks for the pics. It eases my mind somewhat knowing I was not experiencing an unusual problem. I am still going to see if I can't find a different hose to fix it right.
