Looks to me like pretty substantial gains from the back cut thru .700 lift.
The crossover point is probably around .750” lift.
I agree, it LOOKS like the back cut is the way to go, but look at the duration at various lifts with the cam i have. My guess is a cam of .800
net lift like Indy suggests might do well with a back cut? No back cut, 205 and 213 duration at .200 lobe lift, gross lift .868 might fair better
Since the port stalls before .700 lift. Only way to tell is run it, swap to back cut valves after getting a baseline.
The duration at valve lifts is net, after lash is accounted for.
