Any performance A series should have double  valve springs so you can rev them a bit harder than the stock 6500 redline. They are not very expensive. Jeff Taylor at JTS (A series specialist) has them he is in St mary's Sydney 02-96238826. I have a second hand set in the shed you can have dont know how they woudl go as after a few years at 7500+ rpm they are probably just about stuffed.
