340 cam, converter

Def a street vehicle with a great improvement on the powerband. Was reading and looking at 2200-2500 powerband. Was quoted $700 for a refresh on X heads. Was debating if I’m going to end up paying that much to just get aftermarket, but not sure if overkill and what brands work well with 340’s. I am looking for reliability since I’m building it for him just want a healthy 340 with good power.
