Help me choose between two grinds
Since you have LE2 Heads, and your a M6 with a 4.10 Gear I Suggest a 236/236 on a 110-112 LSA Using lobe number 3122 (magnum High lift lobe) 1.6 rocker .608 lift OR 1.5 rocker .570. This is saying your using some very Good Valvetrain. If you don't, forget about it. I like to have around .600 lift on street cars with good heads IMO, I am no expert but this cam will make just as much Peak power than the other cams maybe more and have more power under the curve (throughout the powerband).
The LE2 cam from Bret has some pretty good lift on it as well.

He doesn't want to rev his car to 7K....

Deff the XFI 467, same cam im running, I love it and it's not tuned yet, even so it's only died on me at a red light twice, really had a nice lil pull even from a slow 20-roll, and really opened up the car in the mid-range and topend part. I'm very satisfied with it...Im on stock heads though so I can only imagine what it would do for you and those LE2 heads you got...

That cam wouldn't even peak by 6300 so shifting at 6300 would be a complete waste, his car would be alot faster with a smaller cam.
Ever heard of a Spintron machine my buddies have access to one at Comp, so I get info most people don't know about.
Not all 236 duration cams are the same, they have different Profiles, ramp rates, etc. The High lift version that i listed above is fast and aggresive meaning you don't have to rev it to the moon to make power.

And how exactly would a spintron tell the powercurve of a cam? 
And yes, you would have to rev that cam to ~7K to take full advantage of it.

Why don't you explain how the Spintron fits into this topic
The XFI lobes are pretty aggresive but the High lift XE 3100 lobes and the High lift magnum Lobes have more lift per degree of duration than the XFI lobes even and most of them peak by 6500, hence why I said around 6300-6400 for my selected camshaft.
