what would be a good cam for my application?

since i'm doing a rebuild, i was thinking about throwing in a mild cam. what do you guys recommend? i don't really know whats out there so i don't know where or what to look for. i'm going to be running a pretty much stock motor:

87 gt 5 speed
306 balanced and blueprinted
ross forged pistons
stock rods
stock crank
stock heads (MAYBE mild do-it-yourself port/polishing)
crane 1.6 rr's
cobra intake
65mm tb
70-75mm maf (haven't decided or purchased yet)
24# injectors
u/d crank pulley
bbk cai
hedman longtubes (1.5" primaries 3" collector)
2.5" o/r H pipe
spintech prostreet mufflers
4:10 gurrs
other supporting parts such as fpr, hardened pushrods, double roller timing chain, etc.

should i even get a cam now or should i just wait until i have a few more serious mods? any input is appreciated. Thanks!

i'm actually really interested in having thumper do a set for me. what does he charge? i really want to get a set of heads but money is kind of a big factor right now for me. do you have a # i can have to get in contact with him or something?

thanks for the input guys! looks like i'm going to be sticking with the stocker for now...i'm gonna save up some money and have thumper work an extra set of E7's i got lying around and run stock heads for now. thank again!
