XE268 to Voodoo 03 cam change?

Hi all,
I'm considering changing out my comp cam XE268 can for a Voodoo hydraulic
Advertised Duration (Int/Exh): 268/276
Duration @ .050 (Int/Exh): 226/234
Gross Valve Lift (Int/Exh): .494/.513

Voodoo has a little more duration but approx 25% more lift. Is it worth the effort?
I ask as I have fitted LA X Indy heads from Brian at IMM and they flow more and I could use the lift especially with the improved lift.

I appreciate there are more exotic choices and rollers but I can't afford the latter.

340 motor with 9.7 comp, TTI headers and all the usual upgrades. It is powering a 73 B body so need to keep duration sensible with 3.55 gears.
Car runs wel but I'm leaving quite a lot on the table currently, I think.
