Bob/Em - that car was probably the most unusual engined flatty of many there - you could buy the very nice '32 roadster as seen for $49K with that set up or $29K without. The rest of the car was nice as well - and even me as a long time flathead lover, had never seen that set up and will be doin' my homework.
I thought they were Eelco heads, but are ELCO and at about $2K/set plus the cost of a converted Nash dual plug distributor is WAY beyond my thin wallet (
