Since then, i did a few bleeding (about 8), 6 on 2.1 &  and the rest on 1.9

The 2 last 2.1 i did: I didn't raise the front! At all!!!
Both where water pump replacment. The only difference we saw was that both
engine were running a bit hotter for the first 10/20 miles. Another small
"front" and "rear" bleed fixed the small oveheat problem, some air was still
stuck inside the system on both van.

After a day or 2 both van were running at normal temp, needle at about half
gage.

This is just a comment, i still think that if you have some ramp available
you should raise the front.
