Did you set up your heads or did somebody else do them? Although I agree with you on the spring pressures are not accessive however just what if you put a +.050 locks on one engine to lighten the pressures a bit. Just to try and see if it solves the problem? It would be a inexpensive and real quick thing to do outside of changing your lifters.
Probably irrelevant but what kind of roller rockers are you using?

I actually just talked to a guy in MA that just blew an engine with the same symptoms and same lifters. Likely a different setup. I sent him videos and his motors sounded identical.

RL931 = Morel 4603 = Howard 91162
Morel makes for almost everyone including lunatai, cam motion, PBM, erson, Howard, etc. I put in for warranty with Erson and he said he needed to talk to morel. I'll copy and paste his email later.

I read that there are actually just a handful of lifter manufacturers. I can't confirm it but certainly wouldn't surprise me. It sucks for the OP though as I am pretty certain he won't get credit for them and I wouldn't trust them at this point anyway. Another 2k plus with gaskets etc and a lot of labor.
If/when you end up resolving the problem with some red zones or what ever I would be a huge pain in erson's azz. Sounds like this is a known ongoing problem with some of their lifters. they do have some good cam grinds for what it's worth.
