1586 camshaft

So in rebuilding this DT436B in my 1586, I bought a new FP Diesel replacement camshaft FP 1802337.

Is this the new updated camshaft for the 436B? I cannot measure the new one yet since it's at the machine shop to check the new bearing fit, and I can't find the specs online except to set the valves at .025 and .025 hot or cold, which is the settings for the updated cam per the service manual.

The service manual says the lift is 0.2937 and 0.2935 (somewhere close to there, going by memory) so it's a little more than the DT436 cam at 0.2907 and 0.2905 (again from memory).

The reason I want to know is to get it right because the static timing changed on the 436B to 15 degrees from 18 degrees.

Also, I want to know if that changes any settings in the injector pump since it's at the shop for rebuild and he was talking about some timing plate in it or something for when he gets it in the schedule.

I don't want problems in the future.
 
The higher powered IH 400 series injection pump timing to
crank is 15 degrees BTDC, other engines are set 18 degrees.
No pump changes long as its calibration is set per the ID tag.
