“PermaDry”Timing cover gasket

I found that silicone/steel gasket when I searched up ‘99 magnum on the oreillys website. I thought it would be the same to a ‘94. It had me scratching my head a bit.

Do the later magnums have a different oiling system/passages?

I’ve seen other threads where they mention drilling a hole in the cam thrust plate and the oil plug to get a little more trickle in the chain . Made sense to me so I went ahead and did that
