 Wire size is the way to identify coil spring rates.
100/6s and early 3000s had a wire size of .535”, 225 lbs/in,  free length varies 11” to 12”;
MKII coils are .590”, 330 lbs/in, free length approx. 10-1/2”,
BJ8 coils are .610”, 385 lbs/in, free length approx 10-1/4” long

Thank you so much for taking the time to find this! Very helpful and much appreciated.  I had assumed the opposite when it came to spring length.  Thanks again.

Thanks to the many individuals who helped with my questions concerning coil springs for the Healey.

Below are listed actual measurements of freestanding coil length taken by owners, except for the BN1-4 coil, which was a recollection of one owner.

BN1 to BN4 - 14”-15”  (freestanding coil length)
BN6        - 12”BT7               - 11 13/16”BJ8        - 10 1/8”
 

Coil thickness through BT7 was ½” and for the BJ8 was 5/8”.

So the Healey front coil has become shorter and firmer as it has been upgraded through the years.

More important, a number of owners reported fitting the BJ8 coil to earlier Healeys without problem and said ride height was unchanged or about the same.

I started this thread because Moss recommended the early spring for my BT7 but logically it made more sense to me to install the spring specified at the end of the development cycle (BJ8) than at the beginning (BN1). I am going to buy the BJ8 spring because it will reduce body roll in cornering, handle a little better, and if it has a slightly firmer ride as one owner reported, I can easily tolerate that.
Thanks again,

I have several ft coil springs that I'd like to identify.  I recall that there were 4 variations from the 100 to the BJ8. I believe I have the measurements for the 100, but was wondering if anyone had the specs for the later three? TIA, Shawn
