See Kelly,

I told you Gary was determined

Another "issue" with bolting 4V heads on a 400 engine, the pistons are notched for 2V size valves. I know folks have done this, so there is a solution, I've never paid attention to hot-rodding the 400, my guess is either some company like TRW made pistons for that application, or folks are getting custom pistons manufactured. Kelly is right about the compression ratio issue, I recommend closed chamber heads & a "tight" squish area for max power & detonation control, which would require dished pistons to adjust the CR. Using open chamber heads is cheating
