with .588 lift I should be able to get by with conical or beehive single springs at 360 max pressure.

So yep as I thought, and now you have confirmed... this .620 up stuff iffy. Not saying they don't produce HP, which they do. Not saying others can't get long life, whatever that is. I'm just saying for me, it is the cam motion .621 / .612 or I special order it with .588 / .578. For sure single spring 360 open 6800 rpm cut. If I want more HP, I'll change the pulley.
