1970 Cutlass Supreme headers
I've been looking for headers to put on my Cutlass Supreme. I have a 455 in it and I am having a tough time finding them. It seems like they list them up to 1969 then go from 71 up. What is the big difference?

This BS again.....
Someone, somewhere decided that a Cutlass Supreme was different in some strange way so the "except supreme" footnote started showing up in header catalogs many moons ago and never left even though is has been PROVEN time and time again that there is no difference in the cars. They use the same frame and the bodies are the same from the B pillar forward.
So pay no mind to those notations and just buy you a good set of BBO headers for you car and run with it. Just keep in mind that relocation the proportioning valve to the top of the frame may be in order, so plan for that.

So far the only headers I haven't any complaints about are Dick Miller's.

My only problem was my front springs were SHOT and I bottomed them out quite often because of it and ended up with flat bottomed collectors.

20 years ago when I put a 455 in a 70 Cutlass S I bought Flowtech headers and had no issues with fitment. I don't recall how close the drivers side was the the distribution block, but I know I didn't have to ding anything to get them in.

ARH, I have heard nothing but good stuff, but seems like everybody that bought them around the same the I did had problems. Same thing with Doug's, people that bought the 5-6 years ago say they fit perfect, if you bought the last 2 years they fit like crap.
