Many of you may have seen the urgent broadcast I posted a couple of weeks ago in the Classified section for a set of aluminum heads. 'Brokengate' (Ted) responded and sold me a set of early castings (079) ---thanks again, Ted.  These heads will be used to replace the original heads modified by ace hot rodder, Doane Spencer (most well known for his iconic '32 roadster), in his 1955 Thunderbird which achieved 149.58 mph at Bonneville in 1961.  After a highway accident, parts from the original Tbird were used by Spencer on a donor car to replicate his original car.  The ECL heads had extreme modifications made by Spencer--the heads were ported to an inch of the lives, valve size and position were changed, pushrod location changed, rocker arm spacers custom made, water circulation moved to the top of the heads with custom fab'd transfer tubes, highly modified aluminum dual 4 barrel intake was used, a self ground radical camshaft was installed, the compression ratio was north of 11.5 to 1.  After years of driving on the street, and at least two re-welds, the area around the valve seats could not be successfully repaired---several areas leaked water.  Mummert aluminum heads were chosen to replace the original heads.  Tony Oddo, Jr of TOE Performance, Suisun City, CA is rebuilding the engine with the new aluminum heads to mimic the Ford cast iron units.  The photos below show the transformation:
