Horsepower limit for out of the box Edelbrock RPM heads

Imo, you won’t be able to touch a modified RPM style head, cfm for cfm, hardware for hardware, for what the TF’s are going to cost.
What does someone like Modern charge to CNC a set of SB RPM’s?
Hughes gets $1395 for one version of their full cnc porting, and $1480 for the Big Mouth version. That’s on top of the $1495 for the pair of heads.
And you haven’t upgraded the hardware yet.

The big spring, titanium retainer optioned TF heads will be about $2400/pr.

The TF BB heads aren’t earth shattering in terms of the actual heads themselves........ but in terms of “bang for the buck”, they are clearly on top.
I have no doubt the SB heads will follow in those footsteps.
