I picked up my new Iron eagle heads yesterday. The port sizes on the eagles make my set of 993's look like toys. You can even tell that they are considerably larger than the 186 Double hump heads I was going to use. Got a set of 1.48 X 1.55 intake gaskets and I will have to trim them to make make them work.

What do you think I will gain HP wise over the 993's? I am guessing 80-100 horse. But I might be overly optimistic.
