Cams choice, Low CR vs VE%

So I have actually bought a camshaft from Jones a few months ago, to replace my Hughes Whiplash roller camshaft (208/214) in my 9.6:1 CR 318.

What surprised me, is that he actually recommended me a higher duration camshaft.
HR68340-69340-110
216/220 @.050"
.340"/.340" Lobe Lift
110 LSA

I was expecting a lower duration camshaft for my "low" compression 318.
The .050" duration is a little deceiving, because the seat duration is a lot smaller then most 216/[email protected]" cams. The seat duration is only 264/268.

This will be interesting for sure.
