Head Design ?

[Vic in E-TN]

Is there a single book or paper written showing the design differences and the theoretical advantages of say the Thomas, Winfield, Simmonds and others. I don't want to read a book or books touting any one. I have a pair of Brumfield heads on cars from 15 or 20 years ago and I am happy with their performance but I have a pair of cars that will need better heads next year. Hopefully, Tod will have some for sale.

Thanks,
Vic
