My SM same length as Eddy 72cc E heads -and if pull all the shims out the IH can be near 1.9" with them! I think they are Aussie made from the numbers on the valves.
I have a set of take off E head single springs I'll send you-went with duals for HR. Their valves may not be good enough for solid roller spring pressure-they will tell you that is you ask-some on the 409 heads.. Some of their valves are made by Ferrera but Ferrera will not tell you what quality but hinted more at the 5000 series level.
