Question about using Brumfield head

[mcgarrett]

Yesterday I was fortunate to purchase a new Brumfield head from a private collection of Model A parts being liquidated near me. Apparently it was purchased new in 1995 according to a letter found in the box with the head from Brumfield-Finley in Waco, Texas. I see no trace of scoring on the head stud bosses or any other evidence that it has ever been installed. The letters B-F are the only identification marks cast into the head. It looks like the man that bought it was in the process of smoothing up some of the casting roughness in the combustion chamber and never finished. I plan to finish smoothing out the roughness of the last combustion chamber dome.

Questions:

-With a "B" grind cam and this head with a Model B carburetor and stock A ignition what kind of power increase would be expected from the stock 40 HP?

-What head gasket would be best when using this head? Any guesses about what the compression ratio is? I don't have any idea what the compression ratio is until I contact Brumfield.

-Who else is using a Brumfield head and what is your opinion of its performance characteristics?
