Lol, there's a guy in the H80 thread thinking of dumping the Corsair H80 fans for the Excalibur fans.
Maybe get him to leave temps for you if he goes through the change.
Changing from push to pull or vise versa will only give you differences of a few degrees or less (you could even end up with only a faction of a degree).
Here's a link on some shroud and push vs pull testing with thick fans and normal fans (30mm-25mm):
The chart at the bottom shows a sample of push vs pull with no shrouds. The difference is less than 1c, although only at a 150 Watt load, so it may be slightly higher at higher loads.
If you're OK with the noise, the stock H100 fans are great fans.

You'll get as many fan recommendations as you will a users definition of "Fan Noise" and if in their opinion they are "Loud" or Not!? ... Initially I'd try just the 2 stock fans in a push position, especially If your going to use spacers/shrouds,. It's hard to beat the H100 stock fans for performance although many seem to complain they're too "Loud"
At your overclock/temps I bet you could get away with setting them on "Low", that's what I do for my 24/7 overclock (4.6GHz) and they work fine and are not too noisey for me at that setting
Many of us have found for the average 24/7 overclock that a push/pull config is just overkill ... Law of diminishing returns regarding the heat exchange capacity of the H100 rad and pump/heat block, BUT it is a way to keep temps competitive with the Stock fans while making things quieter with the proper combination if too much "noise" is the concern.
I'm still curious though, what were your ambients for the above temps? I'm guessing 72-75F+ roomtemps?
He could always hook up 40 fans and get some "below freezing" cooling happening.
