They make the round port versions and the D-port version. The round ports will not work with the headers you currently have as they won't bolt up. The D-ports will work fine with the headers you have as far as bolting up to them.
If your iron heads are a true 260 cfm at .500 lift I would stick with them but if you are guessing they are 260 without a flowbench sheet then you might be surprised what they flow... An iron head that flows an honest 260 is a pretty decent head...

He was saying his heads are virgin... it would cost $1000 to get 260cfm. I would go with the edelbrock D ports to keep the same headers if you're on a budget.
