Sorry for the lack of updates.  I went out to California to visit my sister and have been pretty slammed at work.  I went out last week and bought a die grinder, a cutting wheel conversion, 3″ cutting wheels, some quick releases, and some air hose so I could finally use the air compressor I got from my friend.

This allowed me to tackle the task of cutting off the piece of the block that impinged the oil separator on the LS6 valley cover.  I took a picture to show what the cut did.  I think the pictures speak for themselves.
