Ryan, I just installed one of the BLP repair kits in a Ford 3x2 center carb. It's definately a measure twice - cut once deal. After you ream the hole to the right depth, sneaking up on it so you don't ruin the taper at the bottom, make sure you measure the depth and trim the bottom of the insert to length before you Loctite it in. The insert we had was long, and the stackup with the tapered pin and the squirter screw is tight . You'll see what I mean when you get the kit.
