I have heard there were 4 bolt 390's, back in the days of early street racing. there was a guy in my area that was supposed to have had a 390/401hp 4 bolt 63 galaxy never seen his motor but that what was said of his car. i could see this being possible with all the experimenting with different combinations in those days, after all they all are essentially the same motor. I can confirm the 406/405 tri-power 4 bolt, for I used to have one.
