I cant help to ID them but I wouldnt use any MP spring..
to me they are not worth the effort to even ID them...
MP didnt like to give out specs on them... only to say
that they would work on this cam or that one... I had
a set that cam on my W-2s that they said were good to
.640 lift..not saying they were for a FT or roller...
they had a seat pressure of 80#.. I thought they were
just shot so I checked a set of new ones.. same pressure
