My other question, at this point, is, are they worth it? Is a regular lifter, with EDM , a good way to go?

Been there done that with composite lifters, Identical engines some lifters have lived and some didn't and the ones that didn't made a mess in the engine.

Since then I have gone to the Tool steel lifters and no problems so far.
