Incidentally, what would be a good brand/type of engine de-funk-er to use to get rid of the grime that's built up where the intake/exhaust manifold bolts up to the head? I suppose I could always pressure wash it, but I don't have access to a pressure washer, and the one at the coin car wash I went to the other day was disappointingly un-powerful.
