.450 lift cam??

Our rues call for 9.5 to one compression, and 4.50 lift max. Im running a 360 .040 over with Kieth blacks and J heads with 2.02 heads..it has the thick Fel Pro head gaskets. Im not 100% sure its legal on the compression, but thats another problem.
Im curious what you guys run , or would run for a .450 lift cam on this package. It currently has a purple shaft stock 340 cam, but doesn't seem to wake up soon enough. Im pulling around 6300 at the end of the straights. My hope is that I could pick up another 200 rpm or so by picking up some corner speed and a bit better cam
