Lifter ID ?

I don't see why you cannot run them on a higher lift cam, MP sold a .590 lift solid cam kit with those type lifters in the kit. I run that particular cam for years in a street car with no problems and I beat the car like it owed me money.
Very possible there will be no problem. Could be a situation of manufacturing tolerance. Maybe the difference between my old 273 and a newer LA engine. Just posting a previous hair pulling issue, based on (Very) old experience.
