I'm with Vector1 on this one....please, somebody shed a little light on "lash caps".
I realize roller rockers were suppose to reduce the "shearing" effect of a rocker arm slamming down on the top of a valve stem, don't think I ever heard of lash caps.
I envision a device very much like a spring cup that the valve spring sits in on the surface of the head, except on top of the valve/spring assembly. Some sort of variation in thickness could be used to adjust the "lash"....but, perhaps the primary purpose would be to give the tip of the valve stem some protection from the impact of the rocker arm as the valve is actuated.
How far off am I  ?????
