RB in a barracuda, you will most likely need to change the heater motor (Napa has a smaller diameter and shorter one) and if you have power brakes, your booster may hit the valve cover in the driver side.

I am using a RB block with stock type Valvecovers and it cleared no problem. I am sure it will vary car to car however here is a pic of my end result....
