I think this means they are 1973 Lincoln heads, but what does the A2A mean? I plan to use this engine in a mud bogger with a C-6. Any help would be greatly appreciated, Thanx
The "A2A" suffix is not really relevant to anything significant in regards to the engineering design of the cylinder head, and in fact all D3 heads are "D3VE-A2A." D3VE heads were used on 460 engines from 1973-1985.
It would get pretty involved to confirm that your engine is a 1975 model, but suffice it to say that all 1973-1978 460 engines are essentially the same long blocks through those years and that if your engine utililzes a D1VE block then it is likely a 1973-1978 engine. The block's casting number is located on the side of the engine block, behind the starter, and reads vertically.
