Need input from big cam users.

Rick,

oops your right. So I am going to go with the 505. Lash hot 28. Play it safe. Can you explain how lash can be so much different on cams. Could be the Z35 as well. Heck it could be anyone of these. There must be a way to find out. If lash is 28 hot, what would it be cold?

I think I may just bite the bullet and pull the sucker and put a decent hydraulic in. This is crazy.
