Doesn't seem to be any taller than the news tyle dams built in to the newer style heads. Here is a picture of one of the newer draper style heads from the Ohio FSR. The regular platforms have them built in like this too. I know one thing even if it is a disaster and comes off it sure is a whole lot cheaper than buying a pre-made kit for my head. Won't have much out of pocket expense if it does not work out either.
