Free length is less than the stock spring, but I do not see how that matters as long they offer proper load at valve seated height. Load at valve seat height was a little more that stock and more consistent
Load at .380 lift height was roughly 10% greater than stock and more consistent.
Spring rate was a little more than stock springs and very consistent.
Pitch was greater than stock springs, thus allowing for greater valve lift.
It was interesting that the small inner spring had a lower spring rate than the small inner stock springs.
