Only thing I don't know is his cam lift, I think the springs on this head are good to .550"

Ahh, I didn't realize that the ones he has don't flow as well.
In that case, then maybe you should return them Matt. Getting the ones that Batman mentioned could be good, and they will handle any nice streetable cam that you choose.
