LOL I am not against electric fans I run them often and probably will continue to do so. That said lots of lemmings go over the cliff but there are always a few that don't and they keep the tradition alive. Felpro gaskets for the specific heads are a good idea, you measure the ports and go from there. For general information if you don't know how much the block has been decked, or how much has been milled off the heads, or if the intake have been, cut for a specific application is it a good idea to run thick gaskets. Gaskets come in thicker from nearly every manufacturer. I never put sealant on my intake gaskets except around the water ports by the way.
