No offense SVP, but a putting an $8,000 camera on a $400 tripod is an injustice to the camera.
If you're budget only allows for a Manfrotto, then at least get a 504HD head since that has adjustable counterbalance. But I'd suggest looking at the Sachlter Ace tripods as they are dirt cheap & will probably perform better than Manfrotto heads (although I personally haven't tested out any Ace heads, every other Sachlter head I've touched has been great).
Though my personal favorite is Vinten. The Vinten Vision Blue is a steal of a deal at $1,200.

Though I prefer to have a Vinten Blue Head on Manfrotto 535 Sticks (saves on weight).

How many accessories are you putting on the camera? If you're going to add a few additions, and / or use something like a VCT-14 quick release plate, you should look into the Blue 3 or Blue 5 heads as they have a higher counter balance weight range.
Or like Geoff Tirrell mentioned, the FSB 8 is a good head too, plus the counter balance range is superb & goes from something like 4lbs to 20lbs.
The reason I really like Vintens are their perfect balance. Sachtler / Manfrotto have stepped counter balance & you'll need to adjust drag to dial in perfect balance. With Vinten, you can add 2oz & adjust the counter balance spring for the additional 2oz.
But really test these out. If there isn't a vendor near you, e-mail one to see if they (or the manufacture) can send you a demo unit. Actually Vinten, Sachtler & Manfrotto are all owned by the same parent company Vitec, so maybe you can test all three.
