Old Man with a Hat
Yes it has 516 heads, they are okay but small valves and goofy bump in exhaust port. Not something I would call a match with that intake. It is a forged crank engine, cast did not show up till 70s. I would be suspect of cam break in (ran a few minutes?), also ? the forged pistons, pistons in general aren't just everywhere for a 413. If the trans is a 67 up and the shiny stuff on the top of the engine it is probably worth 750-850. I would not buy it with the intention of stroking it, bore size is too small.
