Another "what will it make", but a little different

Well crap. Lol. Well, for now, I will try it, it's all I have for now. I would like to get another set of aluminum heads, really like those airwolf heads. I will just open the chambers up, maybe try concentrate on the area around the intakes to unshroud the valve a little along with dropping the compression?

What kind of numbers do you guys think, even if I have to run a little bit of race gas?
