I'm trying to get ahold of a new set of rings for my 6.0L engine that I'm putting together. I have a 6L block with 27K miles on it that will be getting a cylinder hone, and an LQ9 rotating assembly with 8000 miles on it that is going into the block. I need 4.000" file-fit rings, 1.5mm compression rings and 3mm oil control ring. Where can I get these?
