I've got a 400 and an A833 OD I'm planning on putting in my 75 Dart. I got a stock bottom end with 30 over KB 240 pistons and lunati 10230703LK . Duration is 226/234 @ 50 and lift is .494/.513. planning on buying the weiand action+plus dual plane and 770cfm Holley street avenger. Any recommendations on a decent head that isn't too expensive? I've been looking at the 440 source stealth heads but Is there any other options that are a better bang for your buck?
