Hooker make a set of swap headers,# 2241;

"A" Body Chevelle headers will also fit with a bit of work;

These are what I have in my BBC Monte and here is a link to a blog I made a few years ago on what it took to make them fit;

Unless you are building an all out high performance 427 a set of smaller tube "A" Body Chevelle headers might be a better choice,like these ones;

The smaller 1 3/4 inch primary tube will likely fit a bit better and still give good performance.

Then you don't need the 2 inch tube headers.
They would kill your bottom end.

2 inch primary tube headers will be too big for a Lo Po 427 build.
