Ron,

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.
