Thanks Ed. My problem with light springs is that my variance between the light and real springs is too wide so I couldn't just add.0X. I think I narrowed my problem down to my lash adjustment with the light springs and that was probably because my checking springs were too light. My spring pressures are about 240 on the seat and I use an old Manley tool that was supposed to be used to check spring pressure with the heads on the engine. I'm sure you've seen them or most likely have one. I like not having to take the springs off and put them back on. And my numbers are accurate.

I find the cold/hot lash the same way as you. My question was weather or not the P to V clearance grow like the lash does. Maybe no one really knows. I wonder if the quench grows or does the piston grow too?
