Got a set of lifters that came from Engine Tech that have made in mexico on them. I've done a little research and they are made by Eaton. I tried Melling and Sealed power and they are made in mexico too. My machinist doesn't want to use them but the business I bought them from has been using them since 1992 without issues. Have y'all had any issues with these Eaton lifters? Seems like they make lifters for everybody.
