I have an A2 and installed crower dualsprings & retainers and just to get somewhere I adjusted to helms specs, I was wondering if because I changed the one side from single to dual that are a higher spring rate than the oem on both sides do I use a different measurement?
Please don't answer if you don't have definate answers, this is my first build and I've taken it very seriously! Thanks, Rob.

 

Valve lash is deterined by cam lobe profile design.Valve springs don't have any effect on valve lash.If its an oem cam the oem lash is correct.
