Both you guys need to get a camshaft with more lift to take advantage of the CI head. However you need longer valves so you can use better valve springs & be able to achieve more than .515" of lift.
The ideal cam would be a solid lifter cam with fast rate of lift. Intake duration in the 264+ area & exhaust 270+ with lift at least .550"
My cam is 274/274 with .495" lift. If I went much higher on a street car might not be fun to driver. Even when I talked with Schneider cams he did not recommend that much for a street car. But it is what you want out of the car. I almost went solid for the 250 build.
I'm anxious to see the final results on your 250.
In my opinion i would just advance the cam 2 degrees or since its a 250 straight up my be better.
Remember you will have plenty of torque with the 250 compared to the 200.
