Block is a 71.. head casting number is under the intake ports, you can see it with a mirror if the intake is off

The date code (1C4 on the block) for the heads is located inside the valve covers, in the middle, next to the valve cover rail. Might have to scrape the gunk to see it. You definately don't have the original engine there. It's a 71 block, but no telling, unless you take it apart, as to what parts are there.
