JRP, I've been following for a while... I can't wait to see your results
Maybe when I can afford good heads later I can get a "Gigantor" named after me, too

Having a more aggressive exhaust lobe goes against the convention of most top builders. Snapping the exhaust valve off the seat quicker doesn't do much for power. A slower lobe usually works better on the exhaust side.
This is of course assuming the more aggressive lift on the exhaust side is in fact a more aggressive lobe.
Maybe he is doing that to account for the reverse split.
Looking forward to seeing the results.

I'd make a wager to say the intake lobe falls somewhere in between XE and XE-R though.

I bet the advertised numbers look more like a conventional camshaft with anywhere from 0-4 degrees of foward split.
