I have aa 2017 Streetglide I have checked and found this part does fit my bike but I was wondering do I use the heads I currently have or do I need to purchase new heads separately

This 124" Milwaukee Eight Power Package does not require the purchase of an aftermarket cylinder head to complete the installation. It's totally optional based upon your needs. Here at PartsGiant.com Towers, we like to say that, since you've already got the engine torn down, you might as well add those heads too! After all, you're going for big power with this big bore kit, why not finish the job and avoid any future engine tear downs by adding a set of Milwaukee Eight performance engine heads to your order. :D
