Not that have much doubt what your responces will be but; I have been in constant contact with Booby of BJR racing for a while. He has been essential in the planning phase of my big block build. I am about to make a serious commitment in which Bobby will purchase some heads for me after I send him the money. He is going a long way out of his way to do this for me. I am giving Bobby a good guy vote and would love to hear of your experiences in dealing with this very knowledgeable individual.
