Default Re: 59A adjustable lifters having wear problem

I would NOT recommend using any mismatched parts.
You can have the cam reground.
I would use PROPERLY reconditioned stock steel lifters.

After listening to all of the adjustable lifter problems of the last few years, it may be impossible to get any that will last right now.

Some of the prblems of lifters I have seen come into my shop in the last 5 years:
1 - Loose screws.
2 - Wrong or no taper on face.
3 - Tapered barrel, some up to .004.
4 - Face not square with barrel.
5 - Uneven heat treat throughout especially on face.
6 - Undersize barrel by .003.
