Jack,
I doubt that the heads are interchangeable. To be precise:
"...the 2912cc C-series engine fitted to Austin-Healey 3000s could not be fitted
to the car...Th 'new' 2912cc six-cylinder engine developed specifically for the
MGC, and for the ADO61 Austin 3-litre, was shorter, alittle lighter and somewhat
more compact than before - but it was still a bulky unit"
- from The Mighty MGs, Graham Robson, 1982 (Pub: David and Charles)
in other words it's a different engine.
But he goes on to say that "the Type 29G engine wsa very similar to the ADO61
Austin 3-litre...the most knowledgeable MGC enthusiasts often by the remains of
an Austin 3-litre enge [ie ADO61 engine]. The main features such as the cast
iron block and head are common..." Maybe that is the source of the confusion.
Early Healey engines had green heads often, but they are a LOT earlier than the
MGC and definitely than the post 68 ADO61.
Yes, it was called BLMC. It was BMC in the fifties then in the later sixties
became British Motor Holdings whem BMC merged with Jaguar and British Leyland
Motor Corporation when it merged with Leyland, subsequently it got shortened to
BLMC...and was known as British Leyland or BL then it sort of evaporated [I hope
that I have got that lot in the right order]
