Well I just got up and I called cometic before my first cup of coffee even..
The techline guy said something about the cooling bosses and sealing different..
He said go ahead and run the 5622 but next time order the 5917 s...???
He didn't seem to have enough exact information like I would have liked...
Go ahead and "run um" this is making me overly excited... Somehow I just rather have the correct ones...
