I've had an AMC head on my 2.6 Trooper for maybe two years now. I have had absolutely no issues with it. I should have put it on long ago.

I think your problem lies with the install, some error, or perhaps is a totally separate problem, nothing to do with the AMC head or the installation. Start by looking at the gunk. What kind of gunk is it?
