65 Barracuda 318 Rebuild, Cam, timing, lifters maybe a kit?

maybe desktop is using BBC closed vs open where there is a loss
on a Mopar the open is all on the side away from the port flow
the combustion chamber on the spark plug side on a BBM is basically the same open or closed
on the SBM that is true of the really early head vs the open but the late heads have a much better chamber
you can tell because it does not require so much timing
you can always open up around the valves out to the bore-
the late closed chamber heads flow pretty good IMHO in the half inch lift area- more so than the about 450 for the older heads but IDK at high lifts
that's a place for W heads or high buck or experienced porting on the 360 heads but evidently porting works on the 302's also
what about the late 360 heads?
remember a little hand work on the heads pays a lot of dividends
