my hemi keeps eating its lifters..

Like Perf and IQ said...
Who built it and how many miles are on it? Hemis are unique, World blocks are known to have QC issues, as do Indy heads and rocker systems. To me it sounds like something in the valvetrain is screwed up... More like a head/geometry issue than a lifter issue. IQ mentioned pushrod clearance. If this is a new engine I'd definately look for other problems. The lifters being beaten apart is a sign of a problem - not the problem itself.
