Lifter tick noise, and lifter science

Thanks, I assume NOT is Normal Operating Temperature?:D

Sounds like a good procedure from what we are learning.

Get the engine up to NOT. Rev and hold engine at 2.5k for a min, and increase 500 rpm same amount of time up to 4.5k
Similar to the Rev the shit out of it method.
 
So from what that link site said:

"Lifter Rotation: Flat tappet cams (both hydraulic end mechanical) have the lobes ground on a slight taper and the lifters appear to sit offset from the lobe centerline.This will induce a rotation of the lifter on the lobe.This rotation draws oil to the mating surface between the lifter and the lobe."

Stuck (ticking) lifters that are not rotating are not good for the Cam lobe or lifter bottom lubrication!!!!!
