I was thinking in the .015 to .020 range for lash.. yes, I am fully aware of what lash is, and I also know I'll have to adjust them. This is a twin turbo build that is rather expiramental before I build a real engine with real parts. It is very unlikely that I will be putting loads of miles on this car. I will probably drive it on the street 1 or 2 days a week and hit the track once a week. Frequent adjustment is the least of my worries.
Any why would it matter? this was a roller cam to begin with, I can't imagine that the cam would know the difference between solids and hydraulic roller lifters if the solids are setup correctly, but I could be wrong. I guess we're gonna find out, because I'm not spending money on a cam right now.
