Dude im a seafoam fanatic, its in my oil right now as well as gasoline. Im not sure how i can apply seafoam to this application. Even if i start it with the valves closed it wont get any on the stem. I've been just soaking the piss out of the valves and springs with wd-40, it seems like im just going to have to pull the head off.
