I am in the process of purchasing a 1980 Grans am, I want to put headers on it ! from what I understand the flange or header gasket is unique to the 301? If you look up the gasket 326 to 455 is the same, 301 a different part number
Hooker headers makes Headers for a 1977 to 1980 301 firebird Part # HOK4111HKR, any body ever put firebird headers
on a Gbody here, need help,would they work ? maybe with a little modification ? your help would be greatly appreciated
thanks mike
