If a had one sitting hear I would gladly do it but at this stage I think it would be wasted time. Who in their right mind would pay or port a set of small block heads to the 280cfm area and throw an out of the box (especially dual plane) intake on it. I gotta get this intake finished, flow the exhaust side of the head, and move on to race stuff. I know Hughs did some flow testing with that intake but they may have flowed the intake by itself. I may make up an adapter to try this out of some lexan I have here just for curiosity.
