Default TPiS Headers Install - 1985

I just got finished test installing my ceramic coated tpis headers and y pipe, I got this week (took 2 months to get 'em).
Issues: The flange mounting holes where too small - had to enlarge them in order to install on AFR heads.
At least I didn't need to 'dent' the pipes to make it fit. Weld quality was superb as was the finish. Packaging was excelent to.

Question: What are you guys doing about the proximity to the gas lines? ...and in my case, the headers are close to the clutch master hydraulic hose.

TIA.

I wrapped everything in a heat-resistant tape.

Re-routed them...






Maybe a little overkill, but I really did not like it and the inlet is very accessible on the back of the Miniram fule rails.

The valves in the first pic were removed shortly after the picture was taken. Something about their seals and gas not going together well. The one on the return had been there from the previous owner for some time so I didn't think it would be an issue, but decided not to test fate.

Man that is tight. I guess they left room for the big starter. Almost makes me want to try to make a set myself. If I get a house this year, first thing I'll do is set up the garage. Pneumatics and a welder, and medical lab lighting.
