Well you've done all the basics. I had a similar issue with a 327 one time and it ended up being that aluminum intake. My motor was also pumping oil in the #8 cyl. A guy told me to check that #8 and said to put my old intake back on and viola it was fixed. It has to do with the aftermarket intake not seating off properly on that back corner. Could probably take the intake to a machine shop and have it fixed also.
