As title says. Im looking for stiffer valve springs, i plan to hit very high rpm. I know theres more to it than that, im just tackling this step by step, and i dont need valve float to create an unholy union of piston and valve.
I dont know WHERE to find springs though, has anyone found any? Or even know of valve springs from other vehicles that are easier to find? Im hoping for 11k-12k rpm operation SAFELY
