i have a 1991 camaro(305) and i am replacing the stock heads and manifold with vortec heads and a vortec manifold and i am also planning on installing a XE comp cam 282 roller cam and i am wondering if i will need to have a custom chip burned to accomadate for these changes?

 

Yes, you will. Too often, the engine combination is way off, to never function correctly. It is a good idea to discuss the combination beforehand with the tuner.
