To answere your first question I have used both with no problems - I find some people
leaning towards Dura Bond. With your second question I would go on line and do a little
reading on the subject. sbc has an oil gallery cut behind the bearing so it will get oil no matter
where you put the holes. From what I understand the 4:00 oclock posion is best which would
put your other hole for #1 @12:00 to 1:00
