Think the guy in Texas had a handle of firefighter 3931. They were not B1BA, they were the bigger B1MC heads. Motor was like 430 or 450 cubes and ran 10.20's in a fairly light car.
Good friend local to me has a set of B1BA heads. They are a little better fully ported than an Eddie head. Just take one off headers you have to figure out. Will go 310 or so fully ported, but they make good power.
As i said earlier, the MC head doesn't seem to make power relative to the gaudy 350-360 flow numbers i have heard of. Not ever heard of anyone running them that makes power comparable to a W5 or Indy head. That 10.20 in a light car with lots of cubes is the best i have ever heard of
