Hey Pishta. I measured one and got 1.332" from piston top to top of pin bore. (My dial caliper has sharp edges on the ends of the jaws so I can avoid any added length when measuring to the inside of a hole.)
That works out to a compression height of 1.823" which is not what I expected as that would put it right at 0 deck height with standard crank, rods, and block dimensions. I had to scrape down a few thousandths of carbon to get to the AL piston and get that reading. I can do more of them if you like.
These came out from what we understood to be a virgin 1968 273. The tops look identical to what you show, with 4 small eyebrows and a bevel on the edge.
