Either Don Little or Greg Luneauk are the best that I have ever tried with the big blockMopar Heads. Although both of them a extremely busy and sure do not need my recommendation to have all the work they can handle and more. Brad Van Lant used to run 440/6 Mopar also that was Super Fast and might be able to do them somewhat sooner. E Mail me and I will tell you specifically why I think so as there are some particularly unusual challenges on these heads ......... I have all they above guys numbers and the bills to prove it!
