Just got the numbers done like I did for the 3500 set, and will have to put them on the store tomorrow. Here are the flow specs on the head vs stock manifolds vs ported manifolds.
4.5% flow increase average over stock with the port work. Comparisons with a ported head will come as soon as I port this head so that the numbers are all direct comparisons of the same parts from stock to modified (other than stock manifold testing on the ported head).
