deep pan and windage tray

Even though you are using a 7 quart pan. I assume you will be using all 7 quarts . this will bring the oil level to the same place on the dip stick as the stock pan. Even though there is a baffle there is more oil to slosh around. Spend the extra cash on two pan gaskets and use the Windage tray , it can only help. You may have to cut the tray a little to use the longer pick-up so fit it first before applying the gaskets. This maybe helpful info if not disreguard. Steve
