need help pieceing h/c/i combo

hey guys, im getting a deal on some twisted wedge heads so im planning and pieceing my combo......heres the plan.....i dont wanna rev past 6k so im planning on swaping my performer upper for the performer rpm.....i wanna make power from idle all the way to 6k or even 1500 to 6k would be cool since i have 373s and that would compensate for the low end....heres the problem.....my buddy ran a similar combo a while back and made great power....he had a holley ssytemax/twisted wedge heads/custom cam from FPS.......he parted out the car a while back and gave me his cam.....the cam had a lift of (if i remember correctly) .519/.537......thats all i remember....is there such a place where i can take it and they can tell me the specs of the cam, that way i can know if i can run the cam with my setup or not? my buddy moved and we stopped talking so i cant get the info from him any suggestions?

IF i cannot use this cam, what cam would you guys recommend?
i know custom is the way to go, but what OTS cams would be good for my setup?

thanks guys

good news guys....i contacted fps and got the specs of the cam( although it wasnt easy, i guess they dont like giving out their cam specs). the cam ended up being exactly what i needed and wanted...i just hope it has a nice lope to it how would i know if its a loper or not? in the duration?
