That’s not accurate but it also depends on the build.
Why you haven’t decided to use it yet is beyond me and probably most here.
IMO, No. because the bottom line is it is money spent on something that’s not needed and a most minor amount better at best.
Sounds good to me. But port matching at this level is not going to deliver a great gain. Keep on top of the carb tune until you find the best running and WOT conditions. Pay attention to your plugs as they will tell you all you need to know about the engines running condition.
