I see no Hedman headers listed for your vehicle so exactly what did you buy?
If the headers were bent slightly would they fit?
Here are stock manifolds

Awesome, thanks and I bought just 400 headers that was not vehicle specific should've done more research. They might fit with some modification

I have a set of stock manifolds from a 1978 Catalina with a 400 available if you are interested. Any 77-79 Pontiac 350 or 400 manifolds will work if you can find them.

Where are you located? I would want $25 each plus shipping for them, They will need new down pipe studs as some of them snapped when removing them. Let me know if interested.
