The passages are oddly shaped, with some right-angled turns, with all sorts of nasty casting flaws. Different top-halves are available for mounting a variety of induction setups. Instead, air wants to go over the front of the valve and hit the chamber roof. The pistons are installed following the piston installation procedure outlined in Chapter 8.
