There are other USA sources not discussed which I will leave alone, I personally use Morel, USA made lifters. Only lifter I have found that is true to size .842 +or- .0002 and the roller axle is clipped in rather than crimped which is what causes OD distortion. They are slow bleed and properly heat treated.
4708’s?

Wonder if the "align the hole with" came from the Evo and has just stuck around as common knowledge. Used to be you made sure the hole was pointed inwards. I seem to remember that was even in the old manuals. I still do it just out of habit, whether it matters or not.

Great work Thermo I think they changed from Johnson Lifters in around 2002. I use S&S Premium in my motor on a 619 lift Crane Cam in my 2001. 107 Build. Fueling would probably be a good option. Shame on Harley
