Not any that are commercially available. Though if you have the money I am sure you could get custom ground cams and custom pistons. You need to worry about properly tuning the legend with those things, though, especially the cams as things can go wrong, especially idle and a/f mixture.
yeah idle would be harsh because the valves are overlaping opening and closing but the performance would be good. I wouldnt put it on my daily driven legend but u know my race one might come up some time
