No. I think it likes the split pattern with what you have now. That was why i said give it less lash on the exh (fool it into thinking theres more exh lift and duration) and see what that does. It might want even more and you can run a 1.6 rocker on the exh side too. Or re-cam it. To use a single pattern you need a good relationship between intake and exh port floe, and set of properly sized headers, which in your case I'd bet are a step starting at 1 5/8 and going up to 1 7/8 (2 steps) with tunable collectors. When those parts are working well with each other you can get the single pattern and it will love it.
