Let's not forget the origional intention here, and post, to have a rather small port with good flow, and for 455 based combo (or similar, I'm sure). This is a natural.
The origional plans and conception for our set of 400 cfm HP heads was based on a short stroke 482cid combo.
If they had a bigger combustion chamber, my new 505 Pump gas street motor would have jumped alive with a set of "370 cfm" High-Port heads with the better combustion chamber design and additional air flow, and without a large intake runner volume. But they won't fit under my hood !
