I think that it is starnge for it to have both siamese and single intake ports like this. Improvements can of course still be made, and like Joe said, keep the velocity high. Even if you had access to a flowbench, you still might not be able to get equal flow capability between the siamese and single ports, but doing the best you can do, is still a gain over what you have to start with. Pics also would help. Welcome to Inliners.
