Expected HP & TQ numbers?

Here's engine a local guy is selling. This is his parts breakdown. He's not asking much for it so I'm considering buying it but was curious if someone would have an idea of what these specs might put out in regards to HP and TQ.

-ProComp 190cc Large Port Aluminum Heads with 190cc intake ports with swirl technology 64cc chambers 2.02"x1.60" stainless valves and balancer installed.

-Air-Gap intake manifold

Im guessing 450-475ish. I dont think I will be to far off. the heads are pretty decent and the cam matches pretty good so it should be a stout runner.
