how to drain the stink

I spent the weekend working on the exhaust clearance issue, and figuring out what I want to do for an acetylene torch setup.  I cut the subframe back some more and cleaned it up.  I see three options for the interference issue from last time:

1) modify the subframe:
Pretty substantial. The current header is pointed more or less through the middle of the subframe in structure that I can't just remove. I think I could weld a box tube and some doublers underneath to blow the center section away, but it will be gnarly. Since this subframe is pretty highly stressed, the less I have to chop on it or weld to it the better. As it is I already have to be very careful to make sure I am at least as strong as the original.

2) build a new subframe
Will look cleanest in the end but is the most time consuming.

3) get a different header
Could give me the quick way out if i can find cheap headers.  My first thought is block huggers which outlet straight down near the middle two cylinders.  I think this creates new problems for me (exhuast now outlets where my rack and new subframe are).  Also, block huggers are worst for making power.  My next less intuitive option is to go with a tri-Y:

 

Even though there are more tubes, I lose the flange and the outward cant that is pointing things through the subframe.  To make sure I am not wasting my time, I took some measurements of the image below.  Since I know the distance between the primaries on the engine, I could scale up anything I measured in this image.  I think I may have a collision, but it will be in a different place, and if it is less substantial, I could get away with less subframe modification.  Shipping to me is free, so all it costs me to try is the return trip.  The stakes are big enough, that I figure it is worth a shot.  So I put my bid into the summit fairies. 

 

These are wicked cheap by the way $165.  If they are no good, I may try the block huggers before commiting to the chop and hack campaign.  There is always the kugel option, but that is a long way down at this point: I would have to buy their headers, and their subframe >$1500.  This would also likely mess up my rack location and suck me into their steering arm pieces and the engine frame (>$1700).  So this is sort my whole autonomy at stake here.  Worth a few trips to UPS.
