Should they be real tight on the end of the valve? Is something used to make them stick? Don't want them coming off at all. Do they get peened on?

Oh yeah, in case anyone is interested, I'm back to the 8mm rockers, solid spacer and 911 swivel feet. I think this'll be a sweeeet setup. I'm hoping today to get it all bolted up and start checking the geometry.

Do you need lash caps with 911 svivel feet?

That's what I've been told. The stainless valve stems are soft. The swivels are gentler than solid, but still harder.
