Carb tuning or cam change??

Hi guys! I'm hoping for some experienced opinions from you small block chevy folks. I built this customed out 55 chevy with a 350, pushed out .030 (355)
I had to depend on advice from someone who understood high perf engines 'cause I'm into everything except engine internals. I told him I was looking for the thing to be loud and a little rumpy for the cruises but still streetable. What came about is a mess.
The compression is 11:1 the cam is like the old Duntov 30/30 solid lifter (lift 112/116 duration 254/254) The heads are 462 casting double humps(64cc)
The induction is two 500 edelbrock performer 4bbls on a C26 edelbrock intake.

The thing is loud and rumpy alright but it's also blowing wet black crap out the pipes. I'm sure the vacuum is low with that cam but I haven't checked that yet. Question is, can this thing be street tuned through the carbs or should I be looking at a different cam and lifter set? If so, what would be good with that compression?? Thanks for any and all input. Don't remind me I'm a goof. I know that

pull your plugs!if you ask me that is to much carburation for a 355 engine.
you will need to play with the metering rods and springs.
i think your running way to rich and the cfm's on the carbs are to much for that small of a displacement,if you know someone with 390cfm carbs i would see if you could try them.
