What are you guys running for high lift, high RPM valve springs?
I ran the bullet cams springs this year, but that last couple nights they started to float over 7000 RPM. They are a little thinner then I would like to use.
I have found a couple sites that list specs for motorcycle valve springs that are really close, and I'm sure if I keep looking I will eventually find some that work.
Just wondering if anyone is having them custom made or knows of another performance spring. Something in the .500 lift range
