W2 heads I think they are ready

You can banana groove the oil holes that are in the incorrect location, but that only works up to a point. IIRC that’s about 240ish on the seat, depending on how aggressive the lobe is.

That’s why I just mock it up and move the holes. It’s a PITA but it’s just worth it to make sure the adjusters are getting oil.

It’s not only sad that Chrysler didn’t fix this, but they at least could have released a tech paper on it so end users would know.

Just Edelbrock heads with 273 rockers, but my son and I drilled new holes for his because it is his only car. Hyd. roller with solid roller lifters. Around 180 on the seat. Checks lash twice a year.

I guess what I am saying is take YR's advice, it doesn't really take that much time to do, and it works.
