W2 heads I think they are ready

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?


All I was doing is spreading the available oil.
