Head and cam selection help for 440

ok, so are you saying if using the edelbrocks instead of the trickflows i would need a more radical cam to make the same 550HP?

Yes.

Unless you’re buying something used thats clearly “superior” to the TF head(and there isn’t much that comes to mind for this type of application).......

If buying new ........You can’t get to the level of flow, and overall quality/fit & finish of the TF for the same money.
You can spend more to get there..... but you won’t find it for less, unless someone is giving away free labor.
