Another 149 Piston/rebuilding question

Do the piston heads on a 149 have a front and back orientantion? I have a new kit dished original style and can find no markings for orientation and see no reason it would matter, but tractors are a bit different than cars so IM out of my element.
Also is there a standard orientation for the connecting rods, I think cyl #1 had the bearing tabs on the left side where other 3 were on the right(memory not gospel). It also had some wear at the wrist pin from rubbing the piston, I am nearly certain its been gone through before. Thanks fellas
 
After inspecting the wear on the 1 connecting rod I have surmised that it had in fact been put in backwards. I measured the edge of wrist pin hole to outside of piston head and the wrist pin is dead center and no marking indicating a forward side of piston. So I am going to go with they do not have a front either. Ordered a replacement rod. Hopefully have this thing up and going soon
 
The service manual would give you any information critical to piston and rod direction as well as any special wrist pin orientation.
