I'm pretty sure that both intake and exhaust springs should be the same height 41mm plus one additional shim 0.5mm BUT service manual vol. 1 Engine says 41 + 0.5 for ALL cars after 85/5 where Turbo manual says 41 + 0.5 for intake and 40 + 0.5 for exhaust What value is correct???
Engine 44/52, head p/n 951.104.303.1R

I know it's been beaten to death but I'm putting back head tomorrow and I don't want any more mistakes...

I know that but I don't have them measured (stffness). They are all the same lenght (56mm +/- 0.2mm), I assume stiffness will be more less equall for all of them (hopefully). I went through 100's posts and I'm sure now that exhaust is 40mm, as per Turbo supplement. Well, my initial question was a little retard I think...
