Putting together different configurations for a New Year build, can anybody advise on the major differences between Dewey, Big Boys and Baisley heads? These seem to be the big three head porters everyone is using. At this point I will most likley be using HDWRENCH 98 kit with Woods 6HG cam and probably a pro pipeor T Header. Heads will need to be set up for high lift cam and roller valve train. Budget for head work is around $1000.00. What is the difference in the three Porters?
