Doubtful it is available but I would like to see some ABA testing to see how solid this situation is with a lobe swap.
Just took a look. Pipemax doesn't address the 180s. Does do tryYs though.
I just realized I have been running cylinder specific headers for years..........zoomies.
I use a lot of the Iron Lung headers and its a 4 into 2 and 2 into 1 system for standard fire order cams.
