Trick Flow 440 heads, The Real Deal?

What would you recommend for a solid roller cam for street/strip with these heads on a pump gas stroker looking for 625-650 hp?

Here is one I did with a small HR cam. http://www.forabodiesonly.com/mopar/showthread.php?t=336682

With a solid roller in the high 230's/low 240's, lift at .650"+ this thing would have made 650/700 or damn close to it.
