if you were at a true 10:1, I'd say go for the XE274, but you're not. you may be waaaay off of that. I'd go conservative and go with the XE268, otherwise the car might be pretty doggy until 3500 RPM or so.
 Finally someone brought up the bottom end. I too would go with the 268. Only because of maintaining a nice driveable bottom end. With Stock intake and exhaust, and no plans to mod, it very much sounds like a casual driver. I doubt you want to be hottrodding it all (or even most of the time). The powerband for the 268 should begin about 1800-2000 rpm. The 274 will be higher, probably about 300-400 higher. Having to slip the clutch at 2400 from every stop gets annoying in casual low-performance driving. Sidestepping the pedal while having fun is a different issue.
The 274 is a risky choice in your combo, and it would be held back by the intake/exhaust/compression
