Cam identification help

No expert here but they do have a 590 lift purple camshaft. So if your measurement is off or maybe the cam is worn by .01 you are damned near 590
I had considered that, I will look at it more carefully tonight and measure all of the lines and make sure they all match each other as well, but so far the first 4 and last 4 all have the same measurements, only varying by about .001-.002
