Will a 6 qt be enough?

A piece of 20 gauge sheet metal tie the mains together?

like i said everylitle bit to help out may make a diference my old stock windage tray is very stiff compared to how thin it is and when a piece of metal is clamped down solidly it can act alot stiffer than it looks. i doubt it make a big diference but i dont doubt that it makes a diference,the caps are far out of the rest of the suporting structure of the block and that would indicate to me that there is alot of leverage on them and the tray is even further out making even something fairly thin alot stronger than it looks. but i dont know how much of a diference it makes in the real world..
