ok, Like I said, do you know if they are actually going to work for your motor? Where they set up for it? If a shop looked at them, then why are you posting pictures of them on here? Instead of wasting all the time to install them, and run them. Why dont you measure the ports and determine where the power will be. Port work and engine work, all has to be fine tuned when you put a motor together. It is not something where you just buy the stuff and slap it on. Port work has to be matched to pipes, squish set, compression set, carbs matched, etc.....
