So, some not so great results today. First thing I did was check the compression. Couldn't get the engine started (never good) so I had to check it cold. 125 cold on all cylinders except #1 which was about 70 pounds. Really not good! Pulling the head off tomorrow to visually inspect. Hoping for just a bad ring or something. Motor isn't locked up and as I said ran like a champ for 5 miles coming in, so I'm hoping the thing doesn't need a full rebuild.
