I say yes and no to that because sometimes the available air flow needed for power within the cylinder head that is good for the build is found in, let’s say a TF head, but the low and mid lift numbers are not found else where or cheaply found, just saying for an example…
Just because the heads performance ceiling wasn’t part of the goal or reached… or taxed hard doesn’t mean it’s a waste. Your just using the best part of the head for the task at hand. I would feel guilty or maybe stupid if it was a race build and I didn’t fully utilize the heads potential.
On the wife’s 360, the cam duration is short because it fits the build of the car and it’s parts used. 3.55’s in a 26 inch tire, low-ish stall. This is street cruiser friendly stuff. The cam does lift the valve pretty good (.573) but it doesn’t get into the max head flow area. (.600-.650)
It’s really not needed. It’s only a few cfm more. Not a big loss.
The darn engine just keeps on pulling and pulling!
