General picture of the engine won't help if it's been fitted with the 325 manifolds though.
Head casting number for a 325 of this age is 1705 885, but it's embossed above inlet ports 3 an 4, and is hidden by the inlet manifold when assembled.
However, if you look above exhaust port 2, there should be a small raised circular boss, embossed with the numbers 2.5 and 2.7.
