Peace, mercy, and blessings of God be upon you. I have 6.1 lifters without MDS holes. They fit 6.4 and 5.7. I ordered them, but the problem with my car was not the lifters. This is the reason for selling. They are new in their original packaging and with their oils. Their quality is good, but they are company lifters, not original. They match the original and are without Echo holes. So, you will be fine, God willing 👍🏼 Price: 1350 SAR
