I am not looking at springs to tell me anything regarding current issue of lifter collapse, and that only as a result of a concern voiced that possibility put forth of coil bind caused lifter collapse was result of possible insufficient spring install height.
You still have no idea of whether or not coil bind could be an issue here.
You have not checked the net lift, with a solid lifter, to determine what that is.
This is really very basic stuff here.
You need to know the net lift at the valve with full spring pressure, installed height, and actual coil bind height.
Without knowing for sure what those three things are, you're guessing at best.
"If"(and this is a big if) the actual coil bind height of your springs is at the spec, then based on what I've seen in this thread so far, I think your springs are probably running at about .020-.030 from coil bind.
