Figuring out how much heads have been cut?

Was 8 to 1 even an option in 69? When I was looking before, I thought 80 thou was the furthest down they would be with a stock piston.

I have no idea on the bottom end details other than it's a 69 block, forged crank and LY rods. It runs great and pulls hard so I never worried about it. Previous owner said it ran mid 12s or so, but I never tried.
