Highest flowing sbm heads?

so if Joe Schmo walked in off the street I can only imagine what the bill would be on that build. Wonder if the mill ever ended up in a car?

he has a 66 Belvedere wagon he races ( runs 10.70 with a stock stroke 360 in it, Eddie heads)and has been threatening to stick this motor in it, if it doesn’t sell. He wants 15k complete for it.
at some point, it may well go down the track, thinks it will run bottom 9’s in his Wagon..weighs 3500 or so with him

Edit, the wagon doesn’t have Eddie heads on it, they are those heads like Brian at IMM sold
