Those heads are NOT the desirable ones. They are from a 305 Vortec, and don't have anywhere near the potential of the 062 / 906 heads, even if you do get big valves. Because those 305 Vortec heads don't have the generous short-turn radius that the 062 / 906 heads have.
What's more, there are also swirl-port 305 Vortec heads. Those have even less performance potential.
