Paul, Good to here you got your bits.
Here are photos of the dual spring and retainer sets. They will fit into our $15 worldwide shipping box. Too bad everything won't fit in the small box. $150 USD per set plus $15 shipping worldwide.
1.25" OD with Datsun Comp blue aluminum retainers. (Set has very little use.)
1.14" OD with lightweight stainless retainers and aluminum spring bases.

Hello,
Excuse my ignorance, how many rpm are the dual valve springs you have here good for? I have read that with the right springs you can push the A Series to 8500rpm. I think somewhere else I read the rocker seperating springs need collets or bushes to go this far. I like the idea of 8500rpm max.

These springs are made to go 9000-9500 rpm.
To raise the rpms, we first added a larger oil pump. Next we found that 9000 rpm would require worked rods with better rod bolts (or at least new rod bolts all of the time). When we switched to aftermarket rods we could go to 9500-10,000.
Next we found the valve train weaknesses. Make sure to replace the rocker threads with steel inserts. By using rocker tower studs; or going to 10mm bolts, 10,000 was fine with the A12 (9200-9400 with the A14 and A15).
These springs will safely go 8500 rpm forever, 9200 rpm for a few seasons.
