Stan and fellow vanagon types
I would not spent one second on the OEM heads they crack and recrack. I
would redo AMC heads they are by far a better casting and a better alloy in
fact that's what I typically us on my own vans. The seats are a little
softer than OEM
but they never crack. The guides in the AMC heads are bigger on the OD so
STD guides wont work and the press fit is important. The best method for
guide removal is to core the old guide out this reduces the wall tension and
allows the guide to slide out. This is not a job you can do at home ( ok you
can do this at my house ) but take it to a good shop and have it done right
