The Ford Barn

Turning my old 59A over with the heads off to find TDC, I noticed the pistons do not come up to the top of the deck. They appear to be about 30-40 thousandths from the deck at the top of their stroke. The center of the piston (slight dome, appear stock) barely comes out of the hole. This is all by eyeball, no flat object across the top of the bore or micrometer. I know the motor was rebuilt in the 70's and has very few miles since. It ran well when I pulled it but I never really tested it for power.

Is this normal for a flathead?
