I can't answer the question for how much power they make but I would call TSP and see what they say. You can also check out the dyno section and they might have something close.

We have seen guys move their stage 1 heads over as well. The good news is we can also upgrade you to a larger valve if you'd like us to. We can do 2.04" intakes & 1.60 exhaust in your heads for pretty reasonable money!
