Ok, I was thinking about some things I will need done. First off aamco gave me back the dorman intake manifold, it still has the gasket but there was no lower intake gasket. I was thinking when I decide to put this back on, I might want to put the hv3 or 2 insert in, but first what are the pros and cons of these things? There was a member who was going to sell me one I forgot who it was. Also do anyone know of a site where I can get a clean reservoir coolant tank?
