Advice on Cylinder Head cfm for 340 stroker

And that was sort of the question to you, sorry if it was too vague. But, Oh! I don’t know, 408 - 436 - small block drag car low street useage?
180-200cc how's that for vague, right?
Dialing it back some, I have found the as cast Edelbrock head very good on a mild engine. Ported does well on bopped up mills and mild strokers, not that you couldnt race with them.....
Starting from 177-179cc "ported" would take them to at least 180cc + right?
