They do work well.

And I just love how these gurus always talk about "not" using what a cam might sound like as a precursor to making a decision. LOL nobody goes cam shopping without thinking about how something will sound. Nobody.


I don’t. If a cam grinder brings up idle more than once I move on. If it idles butter smooth and pulls to what ever RPM I want is fine. If it has to idle at 1500 (no cam should ever need that unless you are burning fuel) then so be it.
