Who ported them or will port them? A monkey, you, or a good shop? How much CFM? If you don't know CFM how extensive were they or will the be ported and how bit or the valves?
Factory castings or aftermarket?
No good answer untill you post more info.
A cam and ported intake along with headers will be needed to get max gains.
With stock manifolds and intake.... hardly any gains....
If you want something mild to moderate I have a moderatly ported set of heads with big valves.... Will sell them for $1700 shipped. :)

It depends completely on your current setup, it's not as simple as X heads will give you an X gain.
