Can't tell, I'll pull one off the shelf on Monday and see if it's OE.

The head and manifold gasket type might be the better indicator of a rebuild or major top end service.

also measure the cyl bore to see if it is dead nuts 4.00 inches and not 4.030".

4.000 on the dot.

Measured w/ dial calipers

It is starting to look like you are the first guy to see inside that engine since the 80's.

probably... I know the intake manifold is new-ish, though.
