New heads

What set of heads can I buy and bolt on and run? People have told me that any new heads have to be reworked before you can use them! And what would be the correct heads for a 318ci bored 30 thousands mild cam Tri headers 904 automatic! 69 Dart gt! Thanks

Magnum heads are a nice upgrade if you happen to have a set or can find some at the pull a part. Yes, most would have an exhaust seat cracked but they will run fine. Not everyone's cup of tea, but if you dont mind finagling the intake bolts they are near perfect for a street able low buck 318.
