I have tuned port 350 thats all stock, I want some idle note for cruise nights. Has anyone used or heard this cam?

ZZ3 and ZZ4 use cam # 10185071. This cam has less duration than earlier ZZ mtrs (208/221 @.050) vs 235/235. LSA are also different, 112 vs 114

Using this cam, as it's a roller, it's mild, and the idle has a very slight chop.

For a cruise night ride, you may want to look for something a little wilder.
