The cr will be too high for pump gas. Get a KB dished piston with a -18 to-22cc dish volume for a 400 with 64cc heads and pump gas.
KB147 and KB168 respectively (for 5.7" rod). Use the flat tops in something else.
The XE284H-10 cam will work just fine. Do it right and you will only need to do it once.
If you want to build a pump gas 400 with flat tops. use a 70-72-75cc head.
Why are you asking about the 292H cam when you have a XE284H sitting there?
