Stock 440 rebuild: direction of piston

I have a quick question about a stock 440 rebuild (little mild) that I'm doing. I put the short block together and I realized something I didn't make note of: I didn't make note of which way pistons went into the block.

The top of the piston has two small dimples on the edge. I assembled the short block with all the dimples pointed towards the rear of the motor. Is this correct?

It's been like that in other motors I've worked on in the past. I'm hoping it's correct. It spins nice and freely and doesn't hit anything. I just want to double check. Thank you FABO! :D
