Pretty good numbers! If you want to get the most out of those heads you want to run them on a 4"+ bore to keep the valves unshrouded....but as you see from yours they will still work good, just not to there full potential....if looking for more power ousted to recomend it, but I'd look at a ported FAST 102... But I don't know if it would be worth the money unless you can get a good price for your 92/92 setup you have now
