340 Lifter failure, now what

I do recall a member on here not long ago *****'n about Lunati lifters.
Thats what started my debaucle. I had 2 fail. Went with a set of comp cams and they get noisey after it heats up. Trying to figure out the best way to go. I had no idea so many people were having issues with hydraulic lifters. It is really crazy.
