So I have been doing some research and found there to be several companies to offer head gasket sets (Victor,Fel-pro,Ford oem, and international oem). I ordered the victors and when I got them they were horrible fire rings dancing around in the gasket and just not put together well, so I ordered the fel-pro better but I didnt feel comfortable enough to use them. So I thought I was gonna have to go to ford. I researched the commerical line of the products for the IDI given back then they were in school buses n such and came across FP Diesel which is a subsidiary of Federal Mogul, found a part number for the top end kit and ordered them from napa today has anyone ever used these before in thier truck, I will be updating when I receive them with pics n such.
