Roller Cam Thrust Bearing??

Is there such a thing as a thrust plate for 440 mopars?? I am going to be installing a roller cam into my 440. I have talked with comp cams, but have not really gotten the answer I was looking for. I realize that there are thrust buttons to go between the cam and timing cover to keep the cam in alignment with the lifters, but is a thrust plate or bearing also required between the block and the back of the cam gear?? Any help or advice would be greatly appreciated!

Thanks Again
