Nope, I went with the Comp Cam stage II, but then again I also went with the upgraded springs on Livernois stage III heads. But if you do get it make sure you post your results!!
I am racing and I plan on pushing 7000 rpm, so springs are a must for my build. I can tell you if you are not racing, I would use their cams with those gains. Breenspeed is a reputable company. I'm sure you will do fine.
Look like good numbers for a torque setup. An automatic car would love those. I would still use the Comp springs with them. Cheap insurance against weak springs.
