My 513 bb makes #'s similar to yours and all I use is the Energy Suspension poly motor & transmission mounts.

the only time you need to think about plates is if you have to modify the crossmember making it a problem to use the engine mounts. On our late model we ran solid mounts with a mid plate. That was so we could basically hang the transmission of the engine with just a small support on it's tail. It makes a transmission change alot easier as well
