It would have gone an extra 20wkws or more, a feel alot stronger on the road.Removing intake and exhaust restrictions can help free up valve bounce, as does good strong oil pressure.You'll know when they need upgrading, always shows up on the dyno during a hard power run with power dropping off hard in the high rpm followed by a very shakey idle for a minute or so.
