Turn them so the hole lines up with the holes in the block.
The chart I have says it's a 1969 307 built in Flint, MI on November 9.
No. That would usually be a 283, 307, or 327.
Yes, they should fit ok. 305 heads should bump up the compression a little.
Yes you can.
Sure. All small block Chevy's are the same from 1955 to present. Not sure if the flywheel balance is the same though.
most any small block GM motor, maybe even a big block but im sure u'll rip that transmission out
Although I do not know the answer you need to be more specific. There is more than one small block Chevy. There is the 262, 265, 283, 302, 305, 307, 327, 350, & 400. All of these were small blocks made at different times, but they do not all weigh the same. The basic block weights approximately 181. The weight differences through out the years for the bare block did not vary more than a few pounds.
