I agree, once you start getting into machining stock heads, a set of aftermarket alum heads really becomes more cost effective.
That cam is pretty steep for the 9.4:1 in 350. Your dynamic compression could be pretty low making it feel like a pig down low. A stockish converter with a low stall will make it worse. For comparison, I ran a 230/236 hyd roller in my 408 with a manual and 3.73 gears.
The XE268 may be better for your compression, stall and vehicle weight. Lunati has a Voodoo series worth looking into.
Your best bet...call Reed or Bullet cams and get a recommendation. Be honest about usage, stall, gears, and vehicle weight. They are better at getting you a cam with more lift at a lower duration. I think it is Bullet that also has an asymmetrical exhaust lobe, basically it slows the valve down as it nears closing. It reduces stress on the valvetrain and noise.
The 274 is a BIG step. Over-camming is one of the most common mistakes...

I have a little bit of a rub near lock but if you are turned to lock on a track there are other problems already...
