What do you guys think about these heads

The B1BA heads my brother bought( at Monster Mopar@Norwalk were ported by Hemphill, according to the seller.
my brother bought the complete heads, an intake, and rocker gear for 1200 bucks. This has probably been 5 years ago now.

But these are supposedly the MC version of those heads with the flow numbers listed above. I think they flow in the 350cfm area.
