I have a set of L92 heads and picked up a turbo cam with around .550 lift. (hyd). Now my question is what valve springs to run since its not too radical of lift.. would comp 918s work? Or would the boost (15-20) make them not enough? How does boost factor in with spring selection? How much more spring do you need if so to make up for the extra pressure on the valve? Any? I dont want to excessively over spring it and dont want to under spring it.
