You guys concerned abot leaving it stock could follow Gary Hall's ideas- on one of his go-anywhere cars, he painted a set of aluminum heads Ford Blue after first spraying them with cast-iron paint, so magnet-checks at the track stuck to them!

IMHO, two reasons to change to aluminum heads: the iron heads are 62 lbs heavier than aluminum and all that wt is far above the C.G. That means that if the engine is in the car, changing heads is a two-man job (unless your name is Godzilla!) And second, all the alloy heads run Boss-type adjustable valve trains. One can make iron heads adjustable (the 351-HO had such) but it takes some precision $$$ machining.
