Is there any exhaust manifolds that can be turned backwards in an A body with a 6.4L? If I understand right the bolt pattern will need to be re-drilled but I am OK with that.

Ideally I want to move forward and work on a turbo 5.7 or 6.4(preferably) combo for my 68 Barracuda over the next year or more.

Thank you for any information.
