Flat tops will generally be around 10:1 compression
That will be perfect
Not a whole lot of choice in pistons for a 400, you could always get some custom made

Be damn sure to "clay" the motor or otherwise check the piston to valve clearance after you pick a cam and assemble the motor
You may need to fly cut deeper valve reliefs in your pistons, but I doubt it

Ya'll do realize that this thread is 19 years old and the thread starter hasn't been on since 2008!
