GOESFAST, Thanks so much for taking the time and effort to answer my question. I feel better now, knowing Topline is an excellent replacement.

I don't remember if the original "Johnsons" were flat or did they have a slight crown.
Are the Topline lifters flat or crowned? I do still have an old set of Johnsons lifters that are ground with a slight radius. Is that good, bad or desirable only with certain cams?

Thanks, Jim in FL
