Well guys, thanks for your input. I have to refer back to my original post, I'm not a gearhead, I've never claimed to be and was just trying to get the info from the experts.
I did spend quite some time trying to locate information before I asked. I searched for keywords and phrases that I thought would provide the info I was looking for, unfortunately I wasn't aware at all of the "integrated head", but once I searched for that as Gord suggested I was able to find quite a bit of info.
I do appreciate your input and I received what I was looking for. I'll take your advice for sure and either rebuild the carb I have or purchase another and I'll enjoy the truck for what it is.
