340 Lifter failure, now what

You can get them out with a mopar specific tool. Rick Ehrenburg goes over it in the latest issue of mopar action magazine.

the best lifters are composite faced lifters, very expensive.
I would just buys new cam and lifter package. Alot less headaches breaking in new lifters with a used cam. Rick also goes over correct pushrod length and correct lifter preload in the last 360 aluminum head build of mopar action which was about 4 issues back.
