I am in the process of preparing for a valve grind/cam replacement in my 92 Wrangler with the 4.0 liter. While pricing gasket sets, there have been primarily two manufactures come up: Felpro and Viking. Anyone with any experience in either /or both of these? Seems like the head gasket is pretty important and I really don't want to skimp here. The Felpro are cheaper, but then I can get them anywhere, the Viking can only be purchased at NAPA or Carquest, which are both usually on the heigh end. Any help is appreciated!
