Well guy's, Turbo engine just hit a brick wall. Machine shop just sent the head back as being cracked, and shure, yup it's cracked, they fluxed it, minor but it's there. called DVAP where I bought it, they don't have another, and because it's past 30 days, the only thing they will do is refund after the head is received by them. I'm looking around for another. Memory lane might have 1 but I don't really know. if I have to, I can wait for the new aluminum head to get released late april, and pay the $1,500 for it, and another $400 for the intake needed, that's another 50 HP gaurenteed ontop of 397 HP but I really don't have the funding for that
