By just doing the head swap, it would ease the pain/cost of doing an entire engine swap. That would mean that we could use the BAT pistons, BAT rods, Esslinger oversized valves, Esslinger camshaft, and the any of the Focus performance intake and exhaust manifolds.
All of these parts are already compatible w/ the 95-97 contour zetec except the intake/exhaust Manifolds. Why switch the heads?
