Bruce thanks!
My engine looks a lot different (starter not near there for example), but that BIG cast number is roughly the same place.

but Above the manifold, there appears a more 'offical looking number' and even a date stamp. Could this be more informative, and perhaps what NYS wants?
(I guess this is actually on the head not Block so who knows???)
Also I noted (doesn't show well in this low res pict) at top left of head, just underlip, there is a more recent stamp, using a dotted stamp, (probably hammered in) That perhaps indicates a rebuild or something (I just guessing). Does anyone know what that is?
