Those heads will not work well with such small displacement at rpms where the stock computer can function. The 4500+ rpm comment in their own description is based on a gen 1 intake, the LT1 and 4 intakes shift necessary rpms even higher.
You are building a bench racing dream, I doubt it will live up to your expectations.
Only LTx I know of sucessfully using those heads is a 434ci motor turning 7200 and fed boost and even he choosen ported LT1 heads for street builds. The boost and the displacement both make it capable of using more head than a NA 383 needs.
