Has anyone tried using these?

http://www.ebay.com/itm/DATSUN-1200-G ... -A15-NISSAN-/221271875495

in the description it says "This item is worthy of middle class specifications enough.(To about 8,500-9,000 rpm spec)"

when on the tech wiki it says "The stock A12GX springs are good for 6600 RPM."

do the bproject gx springs really work for 8,500-9,000 rpm?

I have them on my a14 and they fall over at about 6800 with over sized valves. Not high enough for me so i got in contact with Yatala Head Worx and they were able to sort me out

Other wise have a chat to earnie from ATE as he builds high rev race engines too
