well, you could remove the heads, and with a spring compressor remove valve springs, and install new seals. I have never done this and it might be a wives tale from years ago, but I have heard of compressed air into the cylinder, and removing the valve spring with the head in place, and replacing the seal. Worst case if it is valve seal, is removing heads. Blue smoke is burning oil, with the compression test readings, my guess is valve seals. What did the spark plugs look like when you removed them?
