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.
Ok yellow rose can you clarify for me about pushrod length.
I have always followed the old Mopar engine book for optimal pushrod length. But I always thought it was for optimal geometry.
You guys are saying that it was to make sure that those oiling hole line up properly and Pittsburg racer is saying the banana grooves help with this alignment, correct?
