but my understanding is the CCI mount will interfere with the 18mm to AN IN fitting on the end plate.

This is true if the mount plate is the same as mine.  I originally found an odd 90 degree fitting that could be modified to fit (just barely), and that worked fine for the first 3 revs of engine installation. This time around, I plugged that oil inlet hole, and now return oil to the oil filter pad block.  This is how it's done on the FD engine. 

I noticed that you are using the stock oil pressure sender (or appear to). Did you have to purge/fill the portion of the block's tubing with oil to get it to read properly? Is it sending to an EM2 or a separate gauge?

By the way, thanks to you and everyone for the answers thus far..
