Hey everyone,
Got a little dilemma, here. Recently got my hand on an Edmunds Aluminum head for my '55 Flathead. All the bolt holes line up. The only difference is, as opposed to the stock cast head, the 'hump' in the front for the water pump is absent. As you can see in the first photograph, this is how much lip is left once the head is aligned. The little bypass port is exposed. The second picture is just to show the area clearer. Does one plug the bypass? If so, any recommendations on what type of sealant to use to plug this? I've been going crazy trying to figure this out. Any tips would be helpful and appreciated. Thanks!
