Alright, so I'm probably just going to keep the stock springs. Reading MotoIQ's build of their land speed record SR15VET, they used the stock P12 springs and claim they're some of the best OEM springs they've ever seen. They're revving to 8.6k with the 20v cams too. So I should be fine at 9k with the softer ramp up N1 cams.

As for the valve seals, I've seen that site before but when you inquire it lists them as discontinued. So hopefully I can find another engine's valve seals that match or I guess I'll just use the ones in it. I just wanted to be proactive and replace them now.

EDIT: NSX valve seals might work, they're also 5.5mm stem valves. Just need to measure the OD of the guides.
