ENGINE PLATE FOR SLANT 6?

I'm building a full turbo street 6 cylinder and I;'d prefer to use a motor plate setup.

My engine is a Hemi 265 so it's upright but I'd like to know if anyone runs a /6 with a front and mid plate on street?

There are so many opinions about whether it's ok or not.

Let me know guys.

Thanks,

Brett
