Rev kit is a band-aid
Forget those things. Run the correct springs for the application and forget those Dinosaurs.
How can they help with a poor design or cheap made lifter that the pin falls out of the wheel etc.
I dont understand the idle thing either. How can a engine at idle be hard on the lifters? Again another compromise and band-aid for a engine with oiling issue.
Keep away from cheap lifters, and keep spring pressure reasonable, get a valve spring that will control the valve's and run it.
In the end no one is going to know if it will survive or not, about as accurate as playing the lottery and expecting to win
Choose good parts, good assembly technique, along with correct part selection will go a long way.
I dont know about you but I like to make educated guess's off research and past experiance more so than "he said so"
