no.
No. The Pontiac headers will not bolt up to the Chevy small block.
Pontiac 455 headers generally do not fit a Buick 455 due to differences in the engine's exhaust port locations and bolt patterns. While both engines are part of the General Motors family and share some similarities, the specific design and dimensions of the exhaust manifolds and headers vary. If you're looking to upgrade to headers for a Buick 455, it's best to choose headers specifically designed for that engine to ensure proper fit and performance.

YES. They will bolt right up.
No such engine as a Pontiac 400 Big Block. The back of the Pontiac engine block has a different bell-housing bolt pattern than the Chevrolet. Pontiac and Olds bell-housing bolt pattern match. Chevrolet and Buick match. Unless you have a dual bolt pattern transmission (GM did make them) the Pontiac engine won't bolt up to the the Chevrolet transmission.

un bolt the old header and bolt the new one on . dont forget the gasket
Some Pontiacs came from the factory with Chevy engines. If this is the case on your 79 firebird, then the transmission will bolt up to a 350 Chevy. If the car came with a Pontiac engine, then the bolt pattern is different and would not bolt up.
