Just for interests sake, here are some pictures of the Variable Valve Timing setup that the 4.2 uses. In the first picture you get a top down look at the two cams, you can see the VVT hydraulic mechanism sitting on the front of the exhaust cam sprocket. If you look closely, you can also see the brass/copper colored VVT activating valve at the left side of the head, and the extended/enlarged camshaft bearing cap on the exhaust camshaft.
