engine shakes at idle?? HELP!!

hey fellas, i got a 84 351w that was rebuilt and it's a 351w block bored .40 over ,GT-40 heads ,comp cam 35-226-3 specs: gross valve lift .512 ,deration @ .050 int.231 exh.231 , i have edelbrock performer intake and 600cfm carb and it doesnt have headers on it (yet but very soon). and i have the timing set at about 13 with the timing light and i just dont know if i have the timing set bad or what but the truck drives fine ,the engine just shakes at idle and it just doesnt seem right to me. and the reason i rebuilt the engine is that i spun a rod bearing and i also got a new crank and all new bearings. If yall could maybe give me some ideas of what it might be it will reallllly help me out. Thanks Jack
