I don't even bother building serious engines anymore with a cast intake. At the minimum I'll send them to Hughes for their deep port match. If the budget allows then I send the intake to Wilson or I have a local guy do it if he has time. None of the existing Mopar intakes fit very well out of the box. Indy castings tend to be way off and so are Edelbrock. Trick Flow used to be good but the last few I've looked at were way off also.
