IMO, the middle ground between the std rocker gear heads, and the really high end heads are the Indy 360-2’s.
Indy 360-2 cnc230(oval port)-
Used head(but cleaned), Indy 2.10/1.65 valves(back cut on both), and what I believe is the valve job as delivered from Indy.
Tested in December 2015.
4.00” bore, 28” test pressure, no tube on exhaust:
