Glad its working out for you. The opening ramps on the XE series are the next-to-most aggressive speed that Comp uses. Its a fast enough ramp speed to make really nice power without being concerned with accelerated lifter/lobe wear.
Those fast ramp speeds make a flatter and higher torque curve. I had an XE262 in a 468 I built for an old Impala Station wagon. Monster torque from just above idle to 4000. I ended up switching to an XE268 which was fine since I never really needed that much low-end for that car, but I missed the torque of the 262.
