Depends on what you expect out of them. For a mild street set up there not bad. But they will not flow what the X or J head will with the 2.02-1.80.

I'd like to see the proof in that - unless 596s are not all the same - as my set with 202/160s were better than the Js with same valves - especially the exhaust.
Nothing wrong with 596s.
