I have a set of INTENSE stage 3 heads for sale, they have about 3,000 miles on them and are being professionally cleaned and flow tested right now at a head shop in Minnesota. I would like to get $1500 for these, also I do not need a core, so that saves you another 200. I can also work out a sweet deal for you if you need a cam. I have an INTENSE stage 3 cam for sale and my roommate has an INTENSE stage 4 cam for sale. I am somewhat negotiable on the price, so if you are interested let me know.
