irnwkrkev is on a distinguished road

Thinking about the added lift from the 6.4 cam for the MDS lifters isn't quite as much as I thought being that it is pre rocker arms (1.7:1 ratio I believe). It still makes me wonder though as to why they would specify a different part number for the lifters when they seem to have used the same parts on the 6.4 as the 5.7 as often as possible.
