I'm all for a manifold flow test shootout :) Best way would be to 1. flow test each runner left and right 2. At .5 inches of lift increment while they are bolted to the SAME set of heads. 3. Ideally you want a stock head comparison and a fully built 1 mm over head comparison. Testing on stock heads alone will give a skewed result in favor of the lower flowing manifolds.
testing needs to be done on 1 flow bench for accuracy sake.
