You need to put them in so there physically the same way around in the block as they were in the hdi, so valvecut outs at the rear, notchs at the rear, the reason its like it is because the stress during running is on the top bearing shell (rod is under load for compression and firing) which means due to the crank turning clockwise, the stress is on the shell to spin the opposite way, this neesd to be TOWARDS the notch in the bearing shell or else it will round out its notch in no time and spin the shells....
Basically imagine it was a hdi, and put them in the same way, even tho pistons are different, its not that that matters, its the fact the engines rotating the same direction that does
Hope that helps
