my hemi keeps eating its lifters..

Personally, i would contact someone who builds these engines for a living and go with what they reccomend for your application.
Sounds like IQ52 has a lot of experience with them on here, as well as all other engines.
Why not contact him and do what he says? It might cost you a new cam and lifters, push rods and rockers, as well as some clearancing on the block, as well as maybe some springs, but, it will be fixed and done right. So what if it costs you a grand or two, at least it will be reliable and it's potential maximized.
Mike at MRL, Aruzza, or even Larry Shepard would also be go to guys if you would rather deal with someone closer.
If you go any further, the metal shavings you are creating will eventually destroy the engine, What would that be worth?
