My doomed 408 build

Obviously, the cheapest and easiest repair is to pull the one head and just replace the one pair of lifters.
Is that not literally the definition of insanity? Doing the same thing over and over again expecting diffrent results?
If I have had 2 lifter failures in the same hole, I feel something is wrong with the lifter hole not the lifter it's self.
I also know I need to change the springs to any new cam I'm going to run. So both heads have to come off Anyway so might as well put the right ones in. I feel the cost cutting has cost me more money over the long run then doing it correctly the first time.
