Thanks so much. I have read Santucci's book as I said, but there is so much stuff in there it is kind of overload. It helps to be able to get advice specific for my application. I am planning on getting in touch with tlowe, I understand they have sort of a head prep menu over at 12bolt. I talked to my neighbor earlier tonight, he used to run a speed shop in town with his brother, and he recomended a guy for head work. These guys are serious Mopar guys, and anybody doing head work on Mopar should know their stuff. I bought a 70 challenger one time from them, with a 440, sold it to help pay off the house. Regrets, regrets...
