MY opinion only:
It depends on budget, equipment, and goals for the combination.
If you can't afford it, or justify the expense, no
If your building a flat tappet engine for street/strip, and worried about cam breakin, then yes.
Just wanna check for oil leaks, on a factory roller motor? Nope.
Wanna tune a carbed or fuel injected engine for max power, proper a/f ratio, then yep.
Only you can make that decision, depending on your needs and abilities.
I didn't dyno my 406, I will dyno my 522, and 540.
It would have to be one WILD 318 for me to pay to dyno it!
