Like a lot of people I have a 2006 Ford Ranger 72k miles with a misfire and a compression leak. I have decided that I’m going to go ahead and change the heads with some new re-modified Chinese heads. Before I do this big job I was wondering if anyone had any opinions on these Chinese heads? If anyone had any advice on what kind a gaskets to use and if I should replace anything while I’m replacing the heads? Thanks in advance, Chris
