Spent some time last night getting the block prepped, and file-fitting the piston rings. I went with .020" gap on the 1st ring, .022" on the second, and then left the oil rings how they came out of the box. I didn't have to file off much...the Mahle rings already came gapped pretty big. Just waiting for my Manley forged rods to show up....
