Agreed, probably doesn't make much difference. But I also wouldn't be surprised if correct pushrod angles adds some efficiency. One that you can't get in an LA without tracking down a 48 degree block and all the associated parts.
BTW, I'm not trying to goad you or start a fight. Just dialoging. I learned a long time ago that I don't know what I don't know so if someone has an opinion about something, better to listen rather than ignore what might be useful info.
