’69 Dart question

It's got the 904 paired up to the original 273, which is coming out.

I'm putting in a 360, .060" over with the magnum head conversion. Should I keep the 904 or the A999 I've got collecting dust. Will there be fitment issues? Performance or streetability problems? What about all around cost? I'm looking to build for street, not race or daily driving.
