What do you guys think about these heads

Tom Hemphill that owned these heads was very close to the Koffels and they worked on many projects together. Years ago Tom made the first set of billet B1 heads for their dragster the Lake Erie Monster. Well Tom passed away A year or two ago at an early age and his wife is cleaning out the shop and I was told about these heads. I’m just trying to gather info so I can list them for sale for her.

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.
