I've heard the Range chip locking the engine in v8 mode will prevent lifter failure, and some say it doesn't. this article and several others say it will prevent it, so when the chip comes out this summer I'll get one regardless. obviously this makes no difference on the '23's with oversize lifter bores.
They also say a higher quality oil will make a difference, which is kind of a no brainer. I use either Redline or Amsoil Signature in all my good rigs. so that's two things you can do.
Not sure how good the information here is, but it sounds logical.
Do you suspect that your engine's AFM lifter (active fuel management) has symptoms of failure? How can you prevent AFM lifter failure? Here's a guide.
