Thank you for your reply. I am quite partial to Edelbrock parts and the Dave reaffirmed my thoughts of what I wanted to use. The heads are still an issue in referance to what the different valve sizes are and how to figure out the proper combination. I think if I choose a premanufacture set then I don't have a choice on valve size anyway. So I will try them out and if they don't do what I want them to then I can always replace them.
