I'm hoping to do this to my heads which were milled too much and left bottom port too thin. Hope to JB weld 1/8" thick aluminum bar to the head and hope it holds. THink this will work? I tested it on another peice of material and it seems to hold pretty strong
I have some JB Weld here now to perform something like this. Additionally I have used 3M 8115 as well. This is some pretty strong adhesive but I would not use it on the inside of the intake manifold, since I'm doubtfull about its usefullness in heated applications. However there are others.
I know the 3M 8115 from body applications. Today the mayor manufacturers use it every day in their production. The metal will usually shear before the joint will. I know they make adhesives that hold up to more than 200°C no problem. You need to ask around and study each one of them before using it. There are a bunch of these things around.
