Heads for a blown engine? Can they be to big?

I bought 230cc dart aluminum heads for my 383ci. Im going to be running a 177 wieand blower w/ 9lbs boost with a blower profile flat tappet hyd. cam. Are these heads too big? I was told my engine would run better with smaller heads, more like 200cc intake runners. Would it really make a big difference? I already bought the heads and it would be a shame if I had to get different ones. Please give me some opinions. Thanks.

the intake side of the heads are not the problem with a blower...after all air is being forced in but you should try to have very good flowing exhaust ports,etc.
