We spec our own grinds based on in house and track testing here. If you order from somebody, regardless if it is a cam company or another shop , make sure they ask the right questions.
I ordered from several different companies for a dyno cam testing session for a Mopar Muscles article I wrote a few years ago. Only two out of eight companies asked what I consider the correct questions.
Some big companies get by on their names and fancy advertising. A few will try to get you what you really need.
