I'm not sure if the standard cam will be limiting or not but NMS did not say it would be a problem when we were spec'ing my head work and I did say that is what I would be using, but certainly the 285T2 is a very laggy cam, the CVH35 is also I believe (no direct experience myself though), a 285T or a CVH34 are much better and give gains higher up in the rev range without losing out low/midrange.
