Yes, When you change something in the engine you need to make the computer aware of it. The car would run but wouldn't make optimum power or mileage.

243 heads allows you to make alot power,ls6 cam leaves too much on the table .look around for cam choices .TSP combos,PAT-G/EPS cams.take your time ask a lot questions.
