You can never have too much head

No, seriously... You can't.

I have Trick Flow 220's and my car (similar setup to what ur thinking) just kept eating the timing and fuel... That's a good thing.

So long as you can move the air, combust the air, fuel the air, spark the air, and get the air out to start over - you are going to make power. So it is nice to have good heads and not have a problem with air delivery/removal. (normal choke point for a lot of ppl)

I put on ls3 small bores (as cast, just milled) and an ls3 intake and gained 45 rwhp, same dyno, same correction and that was with LS7 manifolds, not headers. I would imagine with headers you will see more gain. They are huge heads for a 5.7, but they worked fine. Very affordable too and an ls3 intake is like a fast already for a fraction of the cost with injectors and rail usually.

There is something to be said about buying new heads vs ported used castings.

OP, you'll be fine with those heads. They were made for the 346.
