ok, I got this '69 cougar for 500 bucks and the guy says that its been re-built and not run. So im taking the heads off of it today and they are quench chambers ! IM REAL HAPPY. the heads are peadestal mount rockers and that means I can build a real nice hydraulic motor cheap so im still happy. Ive never seen or knew that ford made a quench/hydro head- whats the deal with that ? what did it come in ? The pistons are flat tops so tomorrow should be fun.
